About Blood Donation


Blood is the red coloured liquid that flows continuously in our body. Its main function is to transport oxygen and nutrients to all parts of the body to keep it functioning.

The average volume of blood in a healthy adult is about 10-12 water sachets (5.0 -6.0 litres).
Any marked decrease in the quantity of blood requires that the person should be given some blood from another person. This is referred to as blood transfusion. A person who gives blood voluntarily is referred to as a voluntary nonremunerated blood donor.
