Tidal volume is the amount of air that is exchanged during a normal quiet respiratory cycle, which is typically around 500 mL. Residual volume refers to the amount of air that remains in the lungs after a forced expiration and cannot be voluntarily expelled. Vital capacity is the total amount of air that can be exhaled after taking the deepest breath possible. Inspiratory reserve volume refers to the additional amount of air that can be inhaled after a normal inspiration. Expiratory reserve volume is the additional amount of air that can be exhaled after a normal expiration.
