Answer / guest
Blood is the bright red fluid that is pumped from the heart
and is circulating in human body through arteries, veins and
capillaries. It is not a mere liquid, for there are numerous
minute bodies floating in it. These area known as
corpuscles. Some of them are red and some white. Red
corpuscles form nearly one half of the volume of blood.
Hence the colour of the blood is red. White corpuscles are
very little in blood-only 7,500 in one cubic millimeter of
blood. But this meager quantity of white cells is vitally
important for the human body. They perform a very important
function because they have the power to eat up invading
becteria and thus protect the body from disease.
Functions of blood are :
(a) Blood absorbs the food-constituents from the food canal
and distributes them to the tissues. The changes undergone
by the food in different workshops enable the food
constituents to mix with the blood .
(b) Blood absorbs the oxygen contained in the air, which is.
Breathed in and takes it all over the body of oxidation. Red
corpuscles of the blood carry out this function of carrying
the oxygen.
(c) Blood carries away the away the waste materials that are
formed in the tissues to the lungs, kidneys and the skin
from where they are thrown out.
(d) Besides the function given above, blood serves another
important purpose, that of defence. The white corpuscles
constitute the arm y of the human body. When any bacteria
enters the body, it attacks the tissues and causes
disease. The white corpuscles fight with the bacteria,
destroy eat it up.
