What term describes the liquid portion of blood?

Explanation:
The liquid portion of blood is plasma. Plasma is the pale, yellowish fluid that carries blood cells and a variety of dissolved substances—water, proteins (including fibrinogen), electrolytes, nutrients, hormones, and wastes. After centrifugation, you also hear about the buffy coat, which is the thin layer of white blood cells and platelets above the red cells, not the liquid. Serum is what remains after blood clots, lacking the clotting factors like fibrinogen, so it’s not the same as plasma.
