Blood is composed of plasma, red blood cells, white blood cells, and platelets. Plasma makes up approximately 55 percent of the volume of blood. About 7 percent of a personâs weight is blood. An average sized man has about 12 pints of blood and an average woman has about 9 pints. Plasmapheresis is a plasma donation process in which you only donate the straw-colored âliquidâ portion of your blood, the plasma. A needle is placed in the vein of the donorâs arm, and the blood is collected utilizing a highly specialized medical device approved by the Food and Drug Administration (FDA).
