Question

What is the total oxygen carrying capacity of blood?

• A. $20ml/dl$
• B. $10ml/dl$
• C. $25ml/dl$
• D. $15ml/dl$

Answer 1

The correct option is A $20ml/dl$

A normal person has about 15 gm (12-16 gm) of Hb Per 100 ml of blood.

1 gm of Hb binds with 1.34 ml of O2O2. Thus, 100 gm blood carries about 20 ml oxygen. So, O2O2 carrying capacity of blood is about 20%

So, the correct answer is '20ml/dl'
