<span style="font-size: small;"> The term acid rain refers
to the fall of acids mixed with rain and snow. The main cause of acid rain is the
gases emitted by the factories and motor vehicles which pollute the atmosphere.
Mainly sulphur dioxide is responsible for acid rain which is produced in the
burning of fossil fuels. This gas is also produced by natural phenomena like
volcanic corruptions; forests fires etc. sulphur dioxide reacts with water vapor
and forms sulphuric acid in the presence of sunlight. This acid gets mixed with
rain water or snow flakes and fall on to the earth. Similarly, motor vehicles
burn petrol and diesel and produce oxides of nitrogen. These oxides produce
nitric acid with rain water. In 1872, Robert Angus smith was the first person
to discover acid rain.</span></div>

the source of gas emission. During the gulf war many oilfield caught fire and
the smoke produced was so much that it reached even up to the Kashmir
valley and turned the snow into black. Acid rain badly affects the marine life.
The reproduction capability of fish gets reduced. Trees defoliate before time
and the crops having edible roots get destroyed. The Taj Mahal at Agra and New
York’s statue of liberty has lost their luster due to
acid rain. Water lily plants get most affected by acid rain.</span></span><!--[if gte mso 9]><xml>

A cave is a natural
opening in the earth that is big enough for a person or animal to enter. Most
caves are formed by the erosive action of rain water or underground water on
rocks such as limestone or dolomite. The water contains dissolved carbon dioxide
which forms dilute carbonic acid. This acid dissolves the rock, forming passages
and large open spaces. Caverns, caves and joint galleries are the result of
this process.</div>

reduce expenditure space shuttle was invented by the US scientists. Space shuttle is a
reusable manned space vehicle with a speed of about 28,000 km. per hour. The
first space shuttle Columbia

kinds of plants. They contain chlorophyll; therefore, they can make their food
by photosynthesis. They lack vascular bundles, i.e. they do not posses xylem
and phloem. Their thallus lacks true roots, shoots and leaves algae include
unicellular plants to very big multicellular plants. They do not form embryo
after sexual reproduction. Commonly, algae are colored and they can grow up to
40 or 60 meters in length.</span></div>

can live in moist places on land, mountains and near trees. A few species of
algae are found on the ice in the Polar Regions
and in hot water springs. Some of the blue- green algae can survive even at
70-80 degree centigrade. Some algae grow on plants and a few complete their
life cycle inside some plants. Many algae are saprophytic and parasitic. The
best known algae are probably the seaweed found at beaches.</span></div>

<span style="mso-tab-count: 1;"> </span>Stratosphere contains negligible amount of water vapor
and dust. Strong jet streams blow in this layer which affects the weather of
the earth. For convenience this layer may be divided into two parts called
stratospheric layer and ozonosphere. Stratospheric layer exists only up to 25
km height and its temperature remains almost constant. Ozonosphere contains
ozone and it exists between 25 km to 40 km. ozone is essential to life on earth
because it acts as a safety shield for the earth. Ozone forms a hot layer by
absorbing about 90% of short ultraviolet rays of sun which are harmful for the life
on earth.<br />

<div class="MsoNormal" style="text-align: left;">
<span style="font-family: Georgia, Times New Roman, serif;">The rain water and the
water from melted ice that reaches under the surface of the earth through pores
and cracks are called underground water. Some underground water may originate
from the steam rising from molten rock materials deep within the earth. Erosive
action of water on limestone rocks turns their pores into such big sink holes
that even a river if that is drained into them would disappear. <st1:placename w:st="on">Fell</st1:placename> <st1:placename w:st="on">Bank</st1:placename> <st1:placetype w:st="on">River</st1:placetype> in <st1:place w:st="on">Yorkshire</st1:place>

<div class="MsoNormal" style="text-align: left;">
<span style="font-family: Georgia, Times New Roman, serif;"> Springs and artesian wells owe their existence to the
flow of underground water. Artesian wells are of great economic importance in
the mountain ringed basins in the semi-arid climatic regions of the world.
There exist more than 18 thousand artesian wells in the world’s largest
artesian basin in Australian. Artesian wells have been sunk in the Terai region
of <st1:country-region w:st="on"><st1:place w:st="on">India</st1:place></st1:country-region>
for irrigation and supply of drinking water. The underground water is very
useful in our daily lives. It not only provides us the drinking water but also
a valuable source of water for irrigation purposes.</span><span style="font-family: Georgia;"><o:p></o:p></span></div>

<span style="font-family: Georgia, 'Times New Roman', serif;">Why are some people left
handed?</span><br />
<div class="MsoNormal" style="text-indent: .5in;">
<span style="font-family: Georgia, Times New Roman, serif;">Most
of the people in the world do most of their work with the help of their right
hands; but 4% of the world population is left handed. If we go through the
history of mankind we find that many of the great men of the world have left
handed. The world famous sculptors Leonardo Ad Vinci and Michelangelo both were
left handed. Parents of the left handed children usually feel worried about
this habit and make efforts to correct it. But psychologists believe that if a
child is a left handed he should not be forced to hanger this habit.<o:p></o:p></span></div>
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjDC3hj4fnIaN5ouiHDcQGZ36WQa43FwOmXbTllYrBa8C2e1RJFuP7C9ISS3s7RjrCdvUblv3JpWdx7G_Xlqjwjhtbj5bp-Tt5cm55C32wwijgr2vIqMsPVt4zCWl56Xjk-And85-Yg2kw/s1600/images.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><span style="font-family: Georgia, Times New Roman, serif;"><img border="0" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjDC3hj4fnIaN5ouiHDcQGZ36WQa43FwOmXbTllYrBa8C2e1RJFuP7C9ISS3s7RjrCdvUblv3JpWdx7G_Xlqjwjhtbj5bp-Tt5cm55C32wwijgr2vIqMsPVt4zCWl56Xjk-And85-Yg2kw/s1600/images.jpg" /></span></a></div>
<div class="separator" style="clear: both; text-align: center;">
<span style="font-family: Georgia, Times New Roman, serif;">People whose right hemisphere of the brain is dominant are left-handers</span></div>
<div class="MsoNormal">
<span style="font-family: Georgia, Times New Roman, serif;"> If we examine the constitution of the body carefully we
will notice that our body is not fully symmetrical. There is a little asymmetry
between the left and right side of the body. Generally right side of the body id
lightly heavier than the left parts. Even the functions of these parts are somewhat
different. Usually the left half of the brain is predominant over the right
half. In such cases, the nerves from the brain cross over at the level of the
neck and go to the right side of the body. Such persons are right handed. Most
people of the world fall under this category. But there are cases where right
half of the brain is predominant over the left, nerves coming our of the brain
pass on to the left parts of the body. Such people perform all their functions
with their left hands. That is why some children write and even eat food with
left hand.<o:p></o:p></span></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<span style="font-family: Georgia, Times New Roman, serif;"> Have you wondered why left hander’s are in such a
minority in comparison to the right hander’s? Scientists have not been able to
solve this riddle till now. Since the number of right hander’s is so large, the
door handles, locks, screwdrivers, and motorcars, musical instruments all are
designed keeping in view the convenience of the right hander’s. Even buttons
are fixed on the right side for the same reason. The left handed people
experience some difficulty in handling all these but get used to the functions
with a little effort.</span></div>

<span style="font-family: Georgia, 'Times New Roman', serif;">How do we digest food?</span><br />
<div class="MsoNormal">
<span style="font-family: Georgia, Times New Roman, serif;"> The human body requires a constant supply of food in
order to carry out its numerous activities. The food we consume performs two
main functions in our body. First, it supplies proteins for the growth of the
body and second, it supplies energy to the tissues for the day to day work.<o:p></o:p></span></div>
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhCEgzz1PGQgeC8ZY8BFwgypKOu_iQcooiVEixzsxQKj25yrCXRkhyGbJCW2SGMlm4uDg9e2pQ8_Lh3eMnk50FKMMearcI8jVwwYigGb-H8sZ5eIX_Qh-HTVxqo5YL8A3QxjFq2FXIxOhU/s1600/system.gif" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><span style="font-family: Georgia, Times New Roman, serif;"><img border="0" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhCEgzz1PGQgeC8ZY8BFwgypKOu_iQcooiVEixzsxQKj25yrCXRkhyGbJCW2SGMlm4uDg9e2pQ8_Lh3eMnk50FKMMearcI8jVwwYigGb-H8sZ5eIX_Qh-HTVxqo5YL8A3QxjFq2FXIxOhU/s1600/system.gif" /></span></a></div>
<div class="separator" style="clear: both; text-align: center;">
</div>
<div class="MsoNormal">
<div style="text-align: center;">
<span style="font-family: Georgia, Times New Roman, serif;">The Human Digestive System</span></div>
</div>
<div class="MsoNormal">
<span style="font-family: Georgia, Times New Roman, serif;"> The process of digestion is very complex and elaborate.
Digestion begins at the mouth. When we chew food, the saliva produced in the
mouth moistens it. The saliva contains a substance called ptyalin, which
converts the starch of the food into simple sugar. This is the first stage of
digestion. Therefore we should swallow the food only after chewing it properly.<o:p></o:p></span></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<span style="font-family: Georgia, Times New Roman, serif;"> After that, the food material passes through the esophagus
to the stomach where the gastric juices get mixed with it. The walls of the
stomach secret juices containing an enzyme called pepsin and hydrochloric acid.
Pepsin breaks down the molecules of proteins into peptones.<o:p></o:p></span></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<span style="font-family: Georgia, Times New Roman, serif;"> From stomach, the food then enters the small intestine,
where it mixes with three other digestive juices- bile, pancreatic juice and
intestinal juice. The liver produces bile. Its main function is to digest the
fats. The pancreatic juice is basic in nature and neutralizes the acids. It
also digests the proteins. The intestinal juice converts sugar into glucose.
Here, many enzymes also mix with the food. The digestion of food mainly takes
place here. The digested food is them absorbed by the blood vessels present in
the wall of small intestine. The remaining waste of the food now goes to the
large intestine and is finally excreted out of the body as faeces through the
anus.</span></div>

<span style="font-family: Georgia, 'Times New Roman', serif;">How do intoxicants affect
our body?</span><br />
<div class="MsoNormal">
<span style="font-family: Georgia, Times New Roman, serif;"> Alcohol, wine, cigarettes, bidi, opium, intoxicating hemp
ganja and bhang, cocaine or morphine etc. are known as intoxicants. Many people
indulge in them for various reasons but they have a number of harmful effects
on our health. The uses of these are also considered a social evil.<o:p></o:p></span></div>
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg2sVGh3dcjU7OJYO8axUIBrQfBGTOhCcrRtty2RYmB3epaIVS-AC0ENNhLe1whydPzNdYuSq6KVy7Odijr629Ha_3f3pVwDho1u5bD-jiz05jL24NqFfI-NIjJ1wP3guNC8yi2YwAd0-E/s1600/al.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><span style="font-family: Georgia, Times New Roman, serif;"><img border="0" height="292" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg2sVGh3dcjU7OJYO8axUIBrQfBGTOhCcrRtty2RYmB3epaIVS-AC0ENNhLe1whydPzNdYuSq6KVy7Odijr629Ha_3f3pVwDho1u5bD-jiz05jL24NqFfI-NIjJ1wP3guNC8yi2YwAd0-E/s320/al.jpg" width="320" /></span></a></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<span style="font-family: Georgia, Times New Roman, serif;"> People generally consume tobacco in the form of bidi,
cigarettes or Hubble bubble hookah. Some people chew it raw. Tobacco contains a
powerful poison called nicotine and 26 other poisons. Even though it is contained
in extremely minute quantities, they harm our body to great extent. When we
smoke, our blood absorbs some of the nicotine. This nicotine excites our nose
and throat. This also causes coughing. Smoking increases blood pressure. It
accelerates the heartbeat and cases heart ailments. It also affects the body
temperature and blood circulation. Recent scientific researches have shown that
smoking causes lung cancer too. It has also been proved that smoking shortens
the lifespan of people. Moreover, indigestion, peptic ulcer and cancer of the
mouth are also among its after effects. What is worse is that nicotine is an
addictive substance and those who are used to it find it impossible to give up
smoking.<o:p></o:p></span></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<span style="font-family: Georgia, Times New Roman, serif;"> Use of alcohol in the form of liquor is also very harmful
for our heath. Some people carry the wrong impression that drinking makes the
body more active. But this is far form the truth. All the physical process gets
slowed down when one consumes alcohol. More liquor like whisky, rum or brandy contains
a high degree of alcohol. The alcohol has unsuitable effects on our body. As
soon as it enters our body and mixes with the blood, it immediately starts
influencing some areas of the brain. As a result of this, the individual starts
getting intoxicated. His vision gets disturbed. And his thoughts become
illogical and he finally becomes senseless.<o:p></o:p></span></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<span style="font-family: Georgia, Times New Roman, serif;"> Accidents caused by drunken people are very common these
days. Statistics show that one cut of every five accidents is caused by people
who are drunk. Drinking also reduces the control over muscles. Prolonged
drinking causes dangerous diseases of the liver.<o:p></o:p></span></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<span style="font-family: Georgia, Times New Roman, serif;"> Some people take many types of pills of relieve
themselves of pains and mental tensions. These are very dangerous for health.
Excessive use of these weakens the memory. Once you develop the habit of taking
intoxicants, it becomes very difficult to get ride of them. The use of LSD,
brown sugar, opium, ganja, and charas is certainly an invitation to death.
These substances adversely affect the body and brain and give birth to crimes
in the society. We should, therefore, always avoid using them.<o:p></o:p></span></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<span style="font-family: Georgia, Times New Roman, serif;"> To deal with these problems many reform organizations
have established to treat the patients.</span></div>

<span style="font-family: Georgia, 'Times New Roman', serif;">Why does the blood group
vary from person to person?</span><br />
<div class="MsoNormal">
<span style="font-family: Georgia, Times New Roman, serif;"> Even though the blood of all the human beings looks
alike, in reality, it is not so. Our blood is mainly composed of red blood
corpuscles, white blood corpuscles, platelets and plasma. It has been observed
from microscopic investigations that molecules of antigens found on the surface
of red blood corpuscles are different in different people. Antigen molecules
are a kind of proteins that stimulate the production of antibodies. It is this
difference in the antigen molecules that gives rise to different groups of
blood.<o:p></o:p></span></div>
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgAnPl5FWU9gnur8NxTcTqh-HuXEbjceX0dCJDCuPIoOrOB1GW2wgrLLcF93C-Qyb8ia9xBB-Rq_oNVqIj1HgZ6ubi_qTVTnMd_kIjBC12JncoIRxkFxagUMlOAXvaFnswvyLnENw_nDRo/s1600/BloodTable.PNG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><span style="font-family: Georgia, Times New Roman, serif;"><img border="0" height="218" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgAnPl5FWU9gnur8NxTcTqh-HuXEbjceX0dCJDCuPIoOrOB1GW2wgrLLcF93C-Qyb8ia9xBB-Rq_oNVqIj1HgZ6ubi_qTVTnMd_kIjBC12JncoIRxkFxagUMlOAXvaFnswvyLnENw_nDRo/s320/BloodTable.PNG" width="320" /></span></a></div>
<div class="separator" style="clear: both; text-align: center;">
<span class="mw-headline"><span style="font-family: Georgia, Times New Roman, serif;">Blood Compatibility</span></span></div>
<div class="MsoNormal">
<span style="font-family: Georgia, Times New Roman, serif;"> In the year 1900 Dr Karl Landsteiner discovered two kinds
of antigen- A and B type. He was awarded the Nobel Prize for medicine in 1930
for this discovery. Blood containing A type antigen was classified as A group,
while that containing B type as B group. Subsequently, it was discovered that
the blood of some people contains both A and B type antigens. This type was
classified as AB group. The blood that contained neither A nor B type antigens
was called O group. Thus the blood of all human beings has been divided into
four groups. Studies made till now have revealed the existence of more than 200
groups of human blood.<o:p></o:p></span></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<span style="font-family: Georgia, Times New Roman, serif;"> However, as far as the transfusion of blood of nay
patient is concerned, only the aforesaid four groups of blood are important.
Before transfusing blood to any patient, it is essential to get his blood group
tested. It is very essential to match the blood of the patient with that of the
donor before transfusion. It has been found that the blood of even real
brothers and sisters may not be of the same group. On the other hand, the blood
of two individuals belonging to two different states may be of the same group.<o:p></o:p></span></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<span style="font-family: Georgia, Times New Roman, serif;"> If the wrong blood is transfused to patient, he can die,
because antigens of different classes cannot combine with each other. However,
blood plasma of one individual can be given to another because it is the same
in every body.<o:p></o:p></span></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<span style="font-family: Georgia, Times New Roman, serif;"> Landsteiner and Alexander S. wiener discovered another
important blood antigen in 1940. This additional factor is called the rhesus
antigen or Rh factor.<o:p></o:p></span></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<span style="font-family: Georgia, Times New Roman, serif;"> Rhesus antibodies do not occur in naturally blood groups-
both for<o:p></o:p></span></div>
<div class="MsoNormal">
<span style="font-family: Georgia, Times New Roman, serif;">recipients and donors. AB
groups are called the universal recipients whereas O is the universal donor.</span></div>

<span style="font-family: Georgia, 'Times New Roman', serif;">Why do some people snore
during sleep?</span><br />
<div class="MsoNormal">
<span style="font-family: Georgia, Times New Roman, serif;"> We must have definitely come across people who snore
during sleep. Their mouth remains open and a peculiar sound comes out while
breathing.<o:p></o:p></span></div>
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj1rDMSo273wzyuP0YMntwgJT5FvEekleAP7ynqj0okv7g3V_uTNL6rMoIrJvURlO9mi7U7MSLSygkUVVzjgJdAOqYG4TEnLBity5O4vJHSAXUUVwtWuaUYZmuuL0SgCDYPiSC2MciLtbE/s1600/snoring-6.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><span style="font-family: Georgia, Times New Roman, serif;"><img border="0" height="200" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj1rDMSo273wzyuP0YMntwgJT5FvEekleAP7ynqj0okv7g3V_uTNL6rMoIrJvURlO9mi7U7MSLSygkUVVzjgJdAOqYG4TEnLBity5O4vJHSAXUUVwtWuaUYZmuuL0SgCDYPiSC2MciLtbE/s200/snoring-6.jpg" width="191" /></span></a></div>
<div class="separator" style="clear: both; text-align: center;">
<span style="font-family: Georgia, Times New Roman, serif;">A woman snoring during the sleep</span></div>
<div class="MsoNormal">
<span style="font-family: Georgia, Times New Roman, serif;"> Normally, people breathe through nose. But some peoples
nose remains blocked due to some reason. And thus they breathe also make a
person snore. When we are asleep and breathe through the mouth, the air coming
out caused our soft palate tissue at the back and top of our mouth to flutter
back and forth. Thus, a strange sound of snoring is produced. Often this
vibration also caused cheeks, lips and nostrils to vibrate which produces an
even louder sound. When we are awake, the palate remains tight and, therefore,
no such sound is produced.<o:p></o:p></span></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<span style="font-family: Georgia, Times New Roman, serif;"> If we clean our nose and mouth before sleeping, snoring
can be controlled to some extent. This increases the possibility of breathing
through nose rather than through mouth. If one develops the habit of breathing
through nose, the possibility of snoring is greatly reduced.<o:p></o:p></span></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<span style="font-family: Georgia, Times New Roman, serif;"> Breathing through mouth is harmful for heath. The germs
of many diseases can enter directly into the mouth and cause diseases. If we breathe
through nose, the hairs present in the nose do not allow these germs to enter
into the body. It is, therefore, advisable to develop the habit of breathing
through the nose.</span></div>

<span style="font-family: Georgia;">How is our body
temperature maintained?</span><br />
<div class="MsoNormal">
<span style="font-family: Georgia;"> Man is a homoeothermic or warm blooded creature. His
normal body temperature remains almost constant in all the seasons. The
temperature of the surroundings affects it very little. The normal temperature
of a healthy person remains at 37<sup>0 </sup>F or 98.4<sup>0 </sup>F. as a
result of this, the body remains warm.</span></div>
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg0rFukcHl11P-Gaa7atRCN24FDKEYuE1q0FYFPlQrqter-2MK7UJ9UEL6hdzcSnJTuo0JlEpfDNR8QmJXHnA-sdAUrmZ7q3GTe7LF594Pt6kXsfE1KBHdFRXzxnX7CePnIQPDKfxHlUk8/s1600/363203-3222-32.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg0rFukcHl11P-Gaa7atRCN24FDKEYuE1q0FYFPlQrqter-2MK7UJ9UEL6hdzcSnJTuo0JlEpfDNR8QmJXHnA-sdAUrmZ7q3GTe7LF594Pt6kXsfE1KBHdFRXzxnX7CePnIQPDKfxHlUk8/s1600/363203-3222-32.jpg" /></a></div>
<div class="separator" style="clear: both; text-align: center;">
Human Body normal temperature remains at 37 centigrade degrees</div>
<div class="MsoNormal">
<span style="font-family: Georgia;"> Our body receives heat energy from the food we eat. The
food substances produced heat by the process known as oxidation. Oxidation is a
kind of combustion that takes place in our body. We know that the burning of
fuels produces heat. The oxidation of food produces heat in the similar manner.
The only difference is that burning of fuels produces both heat and light,
while combustion of food produces only heat.<o:p></o:p></span></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<span style="font-family: Georgia;"> The body uses the heat produced by food for doing
different kinds of work. Food such as flour, rice, sugar and potatoes contain
sufficient quantity of carbohydrates. To consume foods containing carbohydrates
is very important and necessary to the body because they keep body warm and
provide it energy. Normally 2500 calories of heat energy is produced every day
in the body of a human being. This energy keeps the body warm and enables its
various organs to do different kinds of works.<o:p></o:p></span></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<span style="font-family: Georgia;"> The temperature center of the brain maintains the
temperature of the body. This center consists of three parts- control center that regulates the temperature of the blood; heating center that raises the
temperature of the blood when it drops; and the cooling center that cools the
blood when the temperature rises.<o:p></o:p></span></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<span style="font-family: Georgia;"> Whenever a disturbance occurs in the temperature center of the brain, the body starts shivering and these results in fever. If the
disturbance occurs in the beating center it causes shivering whereas the
abnormality in the cooling center causes fever in the body. The body always
radiates heat to the surroundings. Whenever we sleep or sit on something, it
becomes warm due to the heat coming out from our body.<o:p></o:p></span></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<span style="font-family: Georgia;"> Many diseases cause a rise in body temperature. This
happens because the body produces more heat than it can give off. Much disease
causing bacteria are killed by even a small increase in the person’s body
temperature. But if the body temperature rises above 44<sup>0 </sup>C, it often
results in death because some important enzymes are destroyed.</span></div>

<span style="font-family: Georgia, 'Times New Roman', serif;">How do female mammals
produce milk?</span><br />
<div class="MsoNormal">
<span style="font-family: Georgia, Times New Roman, serif;"> Mammals are those living beings whose females produce
milk to suckle their young. They are warm-blooded and have well developed
brains. They gibe birth to young ones and feed them with their own milk.
Mammals breathe through lungs and their bodies are covered with hair.<o:p></o:p></span></div>

<div class="separator" style="clear: both; text-align: center;">
<span style="font-family: Georgia, Times New Roman, serif;">Internal Structure of Mammary Glands</span></div>
<div class="MsoNormal">
<span style="font-family: Georgia, Times New Roman, serif;"> Milk in the female’s mammals is produced by mammary glands
that are located in the breasts. They are bag shaped and big in size. Shortly
before the birth of her young hormonal changes in the mothers result in
increased development of the mammary glands. They produce large drops of fats
which when mixed with fluids present in the breasts become milk. Corpus luteum
of the ovary also produces a hormone that helps in the process of milk
production. Most of female mammals have tears or nipples form which the young
can suck milk.<o:p></o:p></span></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<span style="font-family: Georgia, Times New Roman, serif;"> At present, there are about 4400 living species of
mammals grouped into 19 orders and about 120 families. They of course, differ
from one another in their bodies, shapes, sizes and habits. Most of them live
on land but some live in water and air also. For example, whales and the
dolphins are mammals, which live in water. And, the bat is a mammal that flies
in the air. They exist in different climatic conditions- hot, cold, dry or
humid. Most mammals give birth to less than 10 young ones a year. Humans
usually give birth to only one baby at a time. Apart from human beings, cow,
buffalo, sheep, goat, etc. also come under the category of mammals.</span></div>

<span style="font-family: Georgia, 'Times New Roman', serif;">How do the ears detect
sound?</span><br />
<div class="MsoNormal" style="text-indent: .5in;">
<span style="font-family: Georgia, Times New Roman, serif;">We
hear a number of sounds every day. Some are pleasant while others are not. On
the basis of its structure the human ear can be divided into there parts external,
middle and internal. Anything producing sound first vibrates. These vibrations
set up a motion of sound waves in the medium through which the sound reaches
our ear. The external ear has large surface and can receive a number of sound
waves at the same time.<o:p></o:p></span></div>
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiuFBBzkEsonm0lYxb_vw2JMcjv0X7RfmXZKKV6h7nHQA1zE3Rx2V6OxakrXE_sIK3gfOGx7SQhKdfkLIk6z7SVd8c5bIt2-aKor0Aa4CCmH-F-c7vRiJF7FG5U2ye7l2Jl0QMGP8Xg5Do/s1600/2191_ear_anatomy_450.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><span style="font-family: Georgia, Times New Roman, serif;"><img border="0" height="290" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiuFBBzkEsonm0lYxb_vw2JMcjv0X7RfmXZKKV6h7nHQA1zE3Rx2V6OxakrXE_sIK3gfOGx7SQhKdfkLIk6z7SVd8c5bIt2-aKor0Aa4CCmH-F-c7vRiJF7FG5U2ye7l2Jl0QMGP8Xg5Do/s320/2191_ear_anatomy_450.jpg" width="320" /></span></a></div>
<div class="separator" style="clear: both; text-align: center;">
<span style="font-family: Georgia, Times New Roman, serif;">The internal structure of human ear</span></div>
<div class="MsoNormal">
<span style="font-family: Georgia, Times New Roman, serif;"> When the sound waves hit the external ear, they are
transmitted to the middle ear through a pipe. The middle part has the ear drum,
which starts vibrating when tenses sound waves hit it. Just behind the ear drum
there are three small bones called hummer anvil and stirrup. As the ear drum
vibrates, these bones also start vibrating. These vibrating are then
transmitted to the cochlea. Which acts like a spring it is surrounded by a fluid
the fluid contains the nerve ending.<o:p></o:p></span></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<span style="font-family: Georgia, Times New Roman, serif;">Due to the vibrations of
cochlea the fluid also starts vibrating and this activates the nerve endings.
The activation of the nerve ending produce impulse which are taken to the brain
the auditory nerve and we hear the sound.<o:p></o:p></span></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<span style="font-family: Georgia, Times New Roman, serif;"> Our ears can detect both feeble and intense sounds with
frequencies ranging from 20 Hz to 20,000 Hz. In the order to keep the ear
healthy, it is essential to produced in the ear, which gets deposited on the
ear drum if it is not cleaned. If this wax accumulates then it can lead of our
ears and consult the ENT expert as soon as there is trouble in the ears.</span></div>

<span style="font-family: Georgia, 'Times New Roman', serif;">Why do we get tired?</span><br />
<div class="MsoNormal">
<span style="font-family: Georgia, Times New Roman, serif;"> Most of us feel tried after working all day long. We also
feel tried after running, swimming or exercising.<o:p></o:p></span></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<span style="font-family: Georgia, Times New Roman, serif;"> When we work at a fast speed, our muscles do not get as
much oxygen as they need. The glycogen stored in our muscles is transformed
into lactic acid through the process of fermentation provide extra energy to
the body. The lactic acid reduces the working capacity of the muscles. This
state of the body is known as muscle fatigue.<o:p></o:p></span></div>
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhCwpTUH6-ItwKR5GijPPTlaK0s6WSVcfPoNggfcW9ztqsWXnejHRDCmHqWjrLngATGlRFF9IoqtqwqweAhkU3-4krXreUWOxuHPiZggVc3XUXdRa-XtUAUrxaVh__VInKOptmzgzj1L4U/s1600/tired_mom.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><span style="font-family: Georgia, Times New Roman, serif;"><img border="0" height="213" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhCwpTUH6-ItwKR5GijPPTlaK0s6WSVcfPoNggfcW9ztqsWXnejHRDCmHqWjrLngATGlRFF9IoqtqwqweAhkU3-4krXreUWOxuHPiZggVc3XUXdRa-XtUAUrxaVh__VInKOptmzgzj1L4U/s320/tired_mom.jpg" width="320" /></span></a></div>

<span style="font-family: Georgia, Times New Roman, serif;">Tired woman</span></div>
<div class="MsoNormal">
<span style="font-family: Georgia, Times New Roman, serif;"> The lactic acid acts as a poison for the muscles. If we
can expel the lactic acid form the muscles by some process, they can again
become fit for working.<o:p></o:p></span></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<span style="font-family: Georgia, Times New Roman, serif;"> As a result of the muscular action, some other substances
called fatigue toxins are also produced in the body. These acids and toxins are
circulated through the body by the blood, because of which both the body and
the brain get tried. Even when we do some mental work, lactic acid and fatigue
toxins are produced in the body and we get tired. Scientists have conducted
many experiments in this field. A dog was made to work hard. And when it got
tired and went to sleep, its blood was transferred into an active dog’s body.<o:p></o:p></span></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<span style="font-family: Georgia, Times New Roman, serif;"> Guess what happened!<o:p></o:p></span></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<span style="font-family: Georgia, Times New Roman, serif;"> The active dog also became tired and fell asleep.
Similarly, if the blood of an active dog is transfused into the body of a tired
dog, it immediately becomes active.<o:p></o:p></span></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<span style="font-family: Georgia, Times New Roman, serif;"> Fatigue is not only chemical process but is a biological
process also. It is a defense mechanism. This warns us to stop working and give
test to the body. Fatigue cannot be removed quickly. It is essential to gibe
rest to the cells of the body to overcome remove fatigue. It repairs the
damaged cells of the body.<o:p></o:p></span></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<span style="font-family: Georgia, Times New Roman, serif;"> When the body receives proper quantity of oxygen through
berating the lactic acid is converted into glycogen and we feel energetic once
again. Little rest also removes fatigue is supplied to some extent by our food
also. That is why a tired person feels very hungry.</span></div>

<span style="font-family: Georgia, 'Times New Roman', serif;">Why do we hiccup?</span><br />
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<span style="font-family: Georgia, Times New Roman, serif;"> Sometimes you begin to hiccup and they just do not seem
to stop, no matter how much you try. At such times, your grandmother might tell
you that someone is remembering you. Some people even say that the person who
is hiccupping has secretly eaten something. All these sayings are mere myths.
Hiccups are just reflex actions by which the body protects itself.<o:p></o:p></span></div>
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEid3l4NHeRBn1gY2_yagV6e_PJuw2QVHYKYFwqgG2Defa-S-VPz2bUowA9Au7V7xQeMqx379Q3KTe1cTTkd93bcQ8voTRfccGgsoWmvnYYh9E8eaWvfbpZcEOTSQUQsi8rtaSSbyi7DMts/s1600/PUL_diaphragm_breathing.gif" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><span style="font-family: Georgia, Times New Roman, serif;"><img border="0" height="220" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEid3l4NHeRBn1gY2_yagV6e_PJuw2QVHYKYFwqgG2Defa-S-VPz2bUowA9Au7V7xQeMqx379Q3KTe1cTTkd93bcQ8voTRfccGgsoWmvnYYh9E8eaWvfbpZcEOTSQUQsi8rtaSSbyi7DMts/s320/PUL_diaphragm_breathing.gif" width="320" /></span></a></div>
<div class="separator" style="clear: both; text-align: center;">
<span style="font-family: Georgia, Times New Roman, serif;">Movement in <span style="text-align: left;">diaphragm when we hiccup</span></span></div>
<div class="MsoNormal">
<span style="font-family: Georgia, Times New Roman, serif;"> Hiccups are short, sharp, and very sudden breaths of air which
happen when our breathing muscles jerk, making us gasp. There is a diaphragm
located between the chest and the stomach. While inhaling air this diaphragm
does down presses the stomach due to which the lungs are filled with air; while
exhaling air, when the diaphragm goes up, the air comes out from the lungs. Thus the diaphragm
goes up and down and the process of respiration continues incessantly without
making any sound. The diaphragm functions like a piston.<o:p></o:p></span></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<span style="font-family: Georgia, Times New Roman, serif;"> Sometimes, due to the formation of gas or increase of
acidity in the stomach, the diaphragm gets irritated and as a result contracts
suddenly. In such a situation, the air passing into the lungs experiences
obstruction and makes a peculiar sound. This is known as a hiccup. It is simply
a process by which the body tries to expel gas or undesirable food material out
of the stomach so that respiration remains unobstructed. Shrinking of the
diaphragm due to drinking or the growth of a tumor near it also causes hiccup.
Hiccups can be cased by eating or drinking too much or too fast. It may also be
an indication of material disorders and brain-stem disease.<o:p></o:p></span></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<span style="font-family: Georgia, Times New Roman, serif;"> Hiccups usually last for a few minutes and disappear if
nothing is done about them. The best way to stop a hiccup is to drink a glass
of cold water because the cold water stops the irritation produced in the
diaphragm and it resumes its normal movements. Holding breath for a while can
also stop hiccups. Sometimes the hiccup stops when one sees something
frightening. If the hiccup does not stop even after a long time, it is
advisable to consult a physician. Generally, in such situation, doctors
prescribe the inhaling of oxygen mixed with 5%- 10% carbon dioxide. Chlorpromazine
also suppresses hiccup.</span></div>

<div class="MsoNormal">
<br /></div>
<div class="MsoNormal" style="text-indent: .5in;">
<span style="font-family: Georgia, Times New Roman, serif;">Just
as an engine needs, fuels like coal, petrol diesel, etc. to run similarly our
body also requires fuel which provides us the energy to work with. The substances,
which act as fuel or energy for our body, are fats and carbohydrates. The food
we consume is burnt with the help of oxygen that we obtain fro breasting and
produces these constituents. The energy, which is released in the process, is
used to perform all our voluntary protein is required for growth and tissue
repair while vitamins and the minerals are necessary for the proper functioning

<span style="font-family: Georgia, Times New Roman, serif;">Nutritious Food</span></div>
<div class="MsoNormal">
<span style="font-family: Georgia, Times New Roman, serif;"> Just as a machine needs pepper fuel, our body requires
nutrients to keep it in proper working condition. The nutrients come from the
food we consume. Our body absorbs and utilizes the useful elements form the
food we eat, and rejects those that are not needed in the form of waster
material. We excrete about 2 kilograms of urine and stools daily. We inhale
oxygen when we breathe and carbon dioxide is produced as a waste material. About
400 gram of water is excreted through the process of sweating.<o:p></o:p></span></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<span style="font-family: Georgia, Times New Roman, serif;"> Human body temperature remains constant between 98<sup>0 </sup>F
and 99<sup>0 </sup>F. There is a
wonderful equilibrium between the production and consumption of heat in the
body so that the body temperature remains constant. Food is measured in units
of energy, called calories.<o:p></o:p></span></div>
<div class="MsoNormal">
<br /></div>
<span style="font-family: Georgia, Times New Roman, serif;"> Our
body is a wonderful machine that works continuously without any break. Even
when we are in sleep, many processes such as respiration, digestion, heart
beating, etc. go on incessantly. These processes also consume fuel
continuously. Eating a balanced and nutritious diet provides the body wit all
its energy requirements.</span></div>

<div style="text-align: center;">
<span style="font-family: Georgia, Times New Roman, serif;">Cholesterol</span></div>
</div>
<div class="MsoNormal">
<span style="font-family: Georgia, Times New Roman, serif;"> Cholesterol is an organic compound belonging to the
steroid family. Occurring either in a <st1:place w:st="on"><st1:state w:st="on">free
state</st1:state></st1:place> of as esters of fatty acid in practically all
animal tissues. The molecular formula for cholesterol is C27 H46 O in a normal
man it is about 0.3% of his average weight. It is the starting material from
which the body produces bile acids asteroid hormones and pro-vitamin substance
in the body. Our body also uses it to help the digestive system.<o:p></o:p></span></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<span style="font-family: Georgia, Times New Roman, serif;"> Cholesterol was discovered in 1812. Its name arises from
its occurrences in gallstones derived from the Greek. Word Chole-stereos-ol
meaning bile-solid. The synthesis of cholesterol occurs in various tissues and
organs particularly the brain liver and arteries. <o:p></o:p></span></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<span style="font-family: Georgia, Times New Roman, serif;"> The increase in its quantity beyond certain level can be harmful
for our body. Execs of fats and cholesterol get deposited in the walls of
arteries causing blockage and hardness thus obstructing the free flow of blood.
This may lead to heart problems. When the arteries get blocked the quantity of
blood flowing in them decreases and as a result the oxygen supply to vital
parts of our body is also decreased. This condition is medically termed as
arteriosclerosis. <o:p></o:p></span></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<span style="font-family: Georgia, Times New Roman, serif;"> High cholesterol deposits may be trap small blood clots
that would normally pass through blood vessels. <o:p></o:p></span></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<span style="font-family: Georgia, Times New Roman, serif;"> We knew that coronary arteries play a vital role for the
proper heart function. They provided oxygen and carry blood to the heart. If a
coronary artery gets blocked that particular part of the heart may stop
functioning leading o a major heart attack which can even prove fatal. <o:p></o:p></span></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<span style="font-family: Georgia, Times New Roman, serif;"> Cholesterol in blood can be controlled by a regulated
diet. A high concentration of cholesterol is present in the foods of animal’s
origin like meat, egg, butter, etc. doctors advise to avoid high cholesterol
food by substituting them with unsaturated foods. Like fruits, vegetables,
reveals and so on. <o:p></o:p></span></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal" style="background: white; line-height: 15.0pt;">
<span style="font-family: Georgia, Times New Roman, serif;"> Lowering
cholesterol levels in the blood can help to reduce the risk of heart attacks.
There are many other measures that can be taken to maintain the desirable
cholesterol level. This includes giving up smoking regular exercises, and
avoidance of overeating and fatty substance.</span></div>

<span style="font-family: Georgia, 'Times New Roman', serif;">How do our muscles work?</span><br />
<div class="MsoNormal" style="text-indent: .5in;">
<span style="font-family: Georgia, Times New Roman, serif;">Whether
we are running waking lifting an object or just getting up from a couch, a
number of muscles come into play. There are about 639 muscles of all shapes and
sizes in the different parts of our body. A medium sized muscles of the body 10
million cells. All the muscles of the body put together have almost 6,000
millions cells. Each of these muscle cells is like a motor. Containing ten
cylinders arranged in a row. The cylinders are tiny boxes that fountain fluid.
A muscle contracts when the brain sends a message to these tiny boxes. For a
fraction of second the fluid in the tiny box congeals and then returns to
normal. It is this action that causes the muscles to move. Muscles make up to
about 40% weight of the body.<o:p></o:p></span></div>
<div class="separator" style="clear: both; text-align: center;">

<div class="separator" style="clear: both; text-align: center;">
<span style="font-family: Georgia, Times New Roman, serif;">Human Muscles Movements</span></div>
<div class="MsoNormal">
<span style="font-family: Georgia, Times New Roman, serif;"> From birth to death, these muscles form a very important
part of our life. They produce heat and help in the movement of food from one
place to another in the digestive system. They take the air to the lunges. If
they stop working all the factions of our body would come of halt. The
throbbing of the heart and the expansion and contraction of intestines would
also stop.<o:p></o:p></span></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
<span style="font-family: Georgia, Times New Roman, serif;"> The muscles of our body are of three kinds striated of
voluntary smooth or involuntary and cardiac. Most of the muscles of the hands
legs neck and head are voluntary because al these limbs function according to
our wishes. Most of them are attached to nuns and are called skeletal muscles.
Striated mussels are made up of many fibers. Smooth or involuntary muscles are
those which functions on their functioning. The muscles of the stomach and
intestine are involuntary because the process of digestion contours on ties
own. These muscles help in blood circulation. The cardiac muscles are found in
the heart. They are also involuntary muscles. They cannot be controlled by our
will. It is most important muscle and is fibrous in structure. With the help of
his muscle the heart beats 2,500 millions times in a life span of 70 days. <o:p></o:p></span></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal" style="background: white; line-height: 15.0pt;">
<span style="font-family: Georgia, Times New Roman, serif;"> Several
body parts such as brain, spinal cord and nerves are involved in the working of
muscles. A muscle is made up to of many tiny fibers that contract when they
receive a signal from the nerve. Muscles fibers either only a few of its fibers
contract the muscles contracts more powerfully when more of its fibers
contract. All muscles work by contraction.</span></div>
