Quizplus · Accepted Answer

Vital capacity refers to the maximum amount of air that can be breathed in and out in one breath, including the amount of air that can still be exhaled after a normal exhalation (tidal volume) and the additional amount that can be exhaled with force after that (expiratory reserve volume). Residual volume refers to the amount of air that remains in the lungs after complete exhalation and is not included in vital capacity.
