Human body
Intestines: These help in the digestion as well as absorption of
food.
Liver: It is the largest gland in the body. Its functions are 1. to secrete bile juice,
which helps in the digestion of food. 2.
to store excess of suger in the form of glycogen. 3. to manufacture red blood
corpuscles, and 4. to help in the production of urea.
Heart: Human heart contains 4 chambers. The functions of the heart are, 1. to supply
pure blood to all parts of the body, 2. to collect impure blood from the organs
of the body and 3. to pump impure blood into lungs for purification.
Lungs: The main functions of lungs are 1. to purify the
blood and 2. to supply oxygen to the blood.
Kidneys : those are a pair of bean shaped glandular organs,
they are a part of the excretory system of human body. They are two in number. They filter the nitrogenous waste of the body
from the blood and throw them in the form of urine.
Skeleton of
Body: The human body is supported on
an internal skeleton consisting of 206 long, short and irregular bones. These are joined together in several modes.
Arteries are blood vessels carrying blood away from the heart.
Veins are the blood vessels which carry blood back to heart
from different parts of the body.
Auricles are two upper chambers of the heart into which the
blood comes from the veins.
Ventricles are the two lower chambers of the heart from which
purified blood flows out through arteries.
Blood is a red coloured fluid circulating through the
heart, arteries, capillaries and veins.
One cubic millimeter of normal blood contains about 50,00,000 red
corpuscles and 6000 white corpuscles. The
red colour of the blood is due to the presence of a pigment known as haemoglobin. The arterial blood is of bright red colour
and the venous blood is of dark red colour.
The total amount of blood is a body is equal to about one-twelfth of the
weight of the body.
Photosynthesis: Plants
manufacture carbohydrates from carbon dioxide and water in the presence of
sunlight and chlorophyll. The process is
called photosynthesis.
6CO2
+ 6H2O Light C6H12O6+O2
Chlorophyll Carbohydrate
Green House Effect: To increase the heat of Earth’s surface is called Green House
Effect. It is caused mainly by the
pollution. Co2 is the
main pollutant in air.
Acid Rain:
The acidic Oxides like SO2, NO2 present in atmosphere and
reacts with water and forms HN3, H2SO4 types
acids and it falls on the earth with rain.
This is called acid rain.
Food Chain:
Food chain is the process of to transfer the energy from one thing to another
thing. It is starts from Herbivorious
and ends with decomposers.
Herbivoriousà Primary Carnivorious à Secondary Cornivorious à Decompossors
Vitamins:
Vitamins are invented by Phunk. There
are two types of vitamins. Those are fat
soluble vitamins and water soluble vitamins.
Vitamin B,C are called water soluble vitamins and A,D,E,K are called fat
soluble vitamins. Vitamins are cofactors
of Enzymes.

Vitamin-A is present in cod, eggs, green vegetables, etc., It is
essential for growth of the body and protects skin and other delicate parts of
the body. It prevents infection and
keeps the eyes healthy. Its deficiency causes night blindness and stunted
growth of the body.
Vitamin-B1 is found in yeast, green vegetables, etc. Its
deficiency leads to beriberi and anaemia.
Vitamin-B2 is the mixture of about twelve components. It is present in milk, butter, vegetables,
etc. This is very important for growth
and blood. The deficiency of this
complex leads to subnormal growth, pellagra etc.,
Vitamin-C is present in vegetables,. Fresh fruits, Oranges and lemons etc.,
Human milk are also a good source of vitamin-C.
its deficiency causes scurvy.
Vitamin-D is present in shark liver oils, milk, butter etc., Its
deficiency causes rickets in children.
Vitamin-E is found in green vegetables eggs etc., Deficiency of
this vitamin causes sterility.
Vitamin-K is mainly confined to green vegetables. This vitamin
maintains normal clotting of blood.
Vitamin-P is present in association with vitamin-C and its
functions are closely associated with the same vitamin. It helps the action of vitamin-C and keeps
the blood capillary healthy.
Water: Most of the food contains water. This constitutes 75 per cent of our
body. It helps the digestion and
absorption of food. It also maintains the
temperature of body and removes waste products.
Balance
diet: it consists of fats,
carbohydrates, proteins, vitamins, mineral salts, in right proportions to
provide the requisite calories. It is
required to be taken regularly and just sufficiently.
