Final answer:
The largest amount of air that can be moved in the lung is called the Vital Capacity (VC), which is the sum of tidal volume, inspiratory reserve volume, and expiratory reserve volume.
Step-by-step explanation:
The largest amount of air that can be moved in the lung is called the Vital Capacity (VC). Vital capacity is the sum of tidal volume, inspiratory reserve volume, and expiratory reserve volume. Tidal volume (TV) is the amount of air that normally enters the lungs during quiet breathing, inspiratory reserve volume (IRV) is the extra volume brought into the lungs during a forced inspiration, and expiratory reserve volume (ERV) is the amount of air that can be forcefully exhaled past a normal tidal expiration. The vital capacity represents the maximum amount of air that a person can move in and out of their lungs.
