Blood plasma is a fluid in a blood that carries the blood components throughout the body. Plasma is the largest part of blood almost 55 percent, wen plasma separated from the body is lightly yellowish liquid. Plasma carries water, salt and enzymes.Te main role of the plasma is to carry nutrients ,and hormone, and proteins to the parts of the body that need it.
