Plasma is the liquid portion of blood and is made up of water, nutrients, and protein. Over half of a person’s blood is composed of plasma.


    Blood contains liquid and solid components. The solid component is made up of red blood cells, white blood cells, and platelets, and the liquid portion is composed of plasma. Plasma distributes nutrients and protein throughout the body, helps the body recover from injury, and removes waste from the body. [1]
