The liquid portion of unclotted blood is called what?

Explanation:
The liquid portion of unclotted blood is plasma. When blood is drawn and not allowed to clot, it remains as whole blood with its cells suspended in a clear, straw-colored fluid called plasma. Plasma contains water, electrolytes, proteins (including clotting factors like fibrinogen), hormones, nutrients, and waste products. If the blood is allowed to clot, the fluid that remains after removing the clot is serum, which lacks clotting factors. The buffy coat is the thin layer between plasma and red blood cells that contains white blood cells and platelets, not a liquid portion. Whole blood refers to the mixture of plasma and cells before separation.
