Quizplus · Accepted Answer

The inspiratory reserve volume is the additional amount of air that can be inhaled after a normal tidal volume inhalation. The tidal volume is the amount of air that is normally inhaled and exhaled during breathing at rest. The expiratory reserve volume is the additional amount of air that can be exhaled after a normal tidal volume exhalation. Adding all three together gives us the vital capacity, which is the maximum amount of air that can be forcefully exhaled after a maximum inhalation. Therefore, the answer is C, vital capacity.
