Question

Under normal physiological conditions, the maximum capacity of O₂ that Hb can carry is approximately:

a. 1000 mls per liter

b. 750 mls per liter

c. 400 mls per liter

d. 200 mls per liter

e. 100 mls per liter

Answer 1

Answer :) 200 mls per liter

Theoretically, the maximum oxygen capacity of Hb is 20.85 ml O₂ per 100 ml blood.

For 1 liter (1000 mL) capacity it would be = 20.85 x 1000/100

For 1 liter (1000 mL) capacity it would be = 20.85 x 10

For 1 liter (1000 mL) capacity it would be = 208.5 ml O₂

The calculated value is near about 200 ml O₂ per liter. Therefore, option d is the correct answer.
