Question #3
The amount of air that remains in the lungs after a normal tidal expiration is the:
A. Functional residual capacity
B. Total lung capacity
C. Vital capacity
D. Inspiratory capacity

Correct Answer: Option A


Explanation:
Functional residual capacity (FRC) is the volume of air in the lungs at the end of a normal expiration (ERV + RV). It prevents alveolar collapse and buffers gas concentrations. Vital capacity is max exhaled after max inhalation, total lung capacity is max air lungs can hold, inspiratory capacity is max inhaled after normal exhalation.
