Which respiratory volume represents the maximum amount of air a person can expel from the lungs after a maximum inhalation effort?
A. Tidal volume
B. Vital capacity✓ Correct Answer
C. Residual volume
D. Inspiratory reserve volume
💡 Solution & Explanation
Vital capacity is the maximum volume of air that can be exhaled following a maximal inhalation, calculated as the sum of tidal volume, inspiratory reserve volume, and expiratory reserve volume. Tidal volume is the normal volume of air inspired or expired during relaxed breathing. Residual volume is the air remaining in the lungs after forced expiration. Inspiratory reserve volume is the extra air inhaled beyond normal resting tidal volume.
