The residual volume is the minimum volume of air that remains in the lungs after a maximal expiration. Tidal volume is the volume of air moved in and out of the lungs during normal breathing. Functional residual capacity is the volume of air remaining in the lungs after a normal expiration. Vital capacity is the maximum volume of air that can be exhaled after a maximal inhalation. Option E is not correct because some air always remains in the lungs after a maximal expiration.
