Question

After deep inspiration, capacity of maximum expiration of lung is called as

• A. Total lung capacity
• B. Functional residual capacity
• C. Vital capacity
• D. Inspiratory capacity

Answer 1

The correct option is C Vital capacity

Vital capacity (VC) is the maximum volume of air a person can breathe in after a forced expiration. This includes expiratory reserve volume (ERV), tidal volume (TV) and inspiratory reserve volume (IRV). In other words, the maximum volume of air a person can breathe out after a forced inspiration is the vital capacity of lungs.

Therefore, the correct answer is option C.
