_______ is a Pale Yellowish Fluid That Contains Red Blood

Question

_______ is a pale yellowish fluid that contains red blood cells, white blood cells, and platelets.
A) Plasma
B) Serum
C) Thrombin
D) Prothrombin

Accepted Answer

Plasma is the pale yellowish fluid that makes up about 55% of whole blood and contains red blood cells, white blood cells, and platelets. Serum is similar to plasma but lacks the clotting factors that are present in plasma. Thrombin and prothrombin are both involved in the blood clotting process, but they are not fluids within the blood itself.
