Importance of blood donation

 Q:        
Importance of blood donation Blood, is a liquid connective tissue which provides the fluid medium for various processes. It carries out the important task of transporting the respiratory gases and providing oxygen to every part of the body.

Thus it is very important for the human body. An average human being contains of 4-6 litres of blood. Blood also plays a major role in the defence mechanism of the body and protects the body from infection and also maintains the body temperature as we are warm blooded animals.

A loss of more than 30 percent of the total blood of the body could be fatal. Such a loss can occur during major accidents, during delivery of a baby, abortion or even surgical operations. Thus, when a person is in need of blood, then this need is fulfilled by some other healthy person.

This proces s is called blood donation. The person giving blood is called blood donor and the one accepting it is called recipient. Blood donation helps save the life of a person and it can bring back a person from the jaws of death. Many blood banks are also established to save lives by blood transfusions.

To donate blood, the blood group of the donor and recipient should be the same. There are 4 types of blood groups: A, B, AB and O. These blood groups have the respective antigens on RBC and the opposite antibody in plasma. If the antigen of the donor and the antibody in the receiver is the same, it causes clotting of blood and the person may die.

Thus it is really important to check the compatibility of blood groups before transfusion. Also, blood group AB has no antibody in plasma hence it cal accept blood from any blood group and hence it is called the universal acceptor and the blood group O has got no antigens on RBC and so it can donate blood to all the blood groups. Hence it is called the universal donor.

Thus, donating blood is the moral and the social responsibility of every citizen of the nation.
