Blood donation is one of the beneficial concept connected with the science of surgical medicine. Like all the inventions borrowed from the West this too is an invention of the scientifically advanced Western countries. Human blood is divided into four groups viz; A,B,0 and AB. This blood is stored and preserved in blood banks for a week or so as it is, and later is preserved in the plasma form.When another human being is struggling for life as cause of loss of blood, in an accident, war ordinary emergency, the blood bank will examine his blood and supply a blood from its storage which corresponds with the blood group of that person. In this way, hundreds of lives have been saved in our country.
