Normal human blood is about:
Correct answer: B. 5l/5000ml of blood
- A. 15ml/100ml of blood
- B. 5l/5000ml of blood
- C. 20ml/100ml of blood
- D. 200ml/100ml of blood
Explanation
The normal human blood volume is typically about 5 liters or 5000ml. In this, the plasma volume is roughly 55% and the remaining 45% is composed of red blood cells, white blood cells, and platelets. Therefore, the approximate amount of blood in terms of volume that is occupied by RBCs is about 20 ml per 100 ml of blood. Hence this is the only correct option. The rest options have incorrect values.
