{Blood plasma} (Physiol.), the colorless fluid of the blood, in which the red and white blood corpuscles are suspended. It may be obtained by centrifuation of blood to remove the blood cells. It is distinguished from {serum} in that plasma still has the fibrin of blood, and may be clotted, while in serum the fibrin has been removed.

{Muscle plasma} (Physiol.), the fundamental part of muscle fibers, a thick, viscid, albuminous fluid contained within the sarcolemma, which on the death of the muscle coagulates to a semisolid mass. [1913 Webster +PJC]
