Question

Which of the following accurately describes plasma?

a. It includes all the blood except the red blood cells.
b. It makes up 30% of whole blood.
c. It is the liquid portion of blood that includes the clotting factors.
d. It is the liquid portion of blood including the formed elements.
e. It contains the blood antigens that determine blood type.

Answer 1

The correct answer is - option C.

Step-by-step explanation:

Plasma is the liquid portion of the blood that carries water, salts, and enzymes in it and comprise almost 55% of the total blood volume. Other 45% of blood contains RBC, WBC, and platelets.

It is a yellow liquid that contains a clotting factor that helps in clotting blood if any injury occurs. Antigens are present on the RBCs not in the blood plasma that determines blood type.
