Plasma is a yellowish liquid that suspends and transports food and wastes to and from all of the body's cells. The plasma carries food particles to the cells of the body where they are converted into energy or stored away for a later need.Plasma is also the medium in which all red blood cells, platelets, and white blood cells are transported around the body.uppfer cells, or hepatic macrophages, are irregularly-shaped, yellow white blood cells that live permanently in the liver. In the liver, they trap, eat, and then recycle worn-out red blood cells. Kupffer cells also remove bacteria and debris using phagocytosis from the blood in the liver.
