Question

Quizplus · Accepted Answer

Vital capacity refers to the maximum amount of air that can be moved in or out of the lungs during a single breath. It is the difference between the maximum amount of air that can be inhaled and the maximum amount of air that can be exhaled. Option A is incorrect as it refers to tidal volume, which is the volume of air exchanged during normal breathing. Option C is incorrect as it refers to total lung capacity, which is the maximum volume that the lungs can hold. Option D is incorrect as it refers to residual volume, which is the volume of air that remains in the lungs after maximum expiration.
