Question

The capacity of lungs for air in a healthy man is

• A. 500 ml
• B. 1000 ml
• C. 1500 ml
• D. 3000 ml
• E. 6000 ml

Answer 1

The correct option is E 6000 ml

Total lung capacity (TLC) is the maximum amount of air the lungs can hold when they are fully inflated. The average total lung capacity of an adult human male is about 6 litres of air. It can be calculated by using the formula TLC = TV + IRV + ERV + RV where TV is tidal volume(500 ml), IRV is inspiratory reserve volume(3100 ml), ERV is expiratory reserve volume (1200 ml) and RV (1200 ml) stands for residual volume.

So, the correct answer is option E.
