What is involved?

Blood transfusion

This is the process of receiving blood products into one's circulation through a vein. Transfusions are used for various medical conditions to replace lost components of the blood. Early transfusions used whole blood, but modern medical practice commonly uses only components of the blood, such as red blood cellswhite blood cellsplasmaclotting factors, and platelets.

Blood donation

Blood is most commonly donated as whole blood taken from a vein. It then goes through the blood bank for testing, separation into components and storage prior to distribution where it is needed.
