Question

What does blood consists of?

• A. 60% plasma, 40% corpuscles
• B. 40% plasma, 60% corpuscles
• C. 25% plasma, 75% corpuscles
• D. 90% plasma, 10% corpuscles

Answer 1

Answer: (A)

60% plasma, 40% corpuscles

Plasma is the fluid component in which the blood cells are suspended. These blood cells include

Red blood cells (erythrocytes) - carry oxygen from the lungs to the rest of the body.

White blood cells (leukocytes) - help fight infections and aid in the immune process.

Platelets (thrombocytes) - help in blood clotting.

Whole blood contains red cells, white cells, and platelets (~45% of volume) suspended in plasma (~55% of volume). Thus, option A is correct.
