Quizplus · Accepted Answer

Tidal volume is the amount of air moved in and out of the lungs during a normal, quiet respiration. Dead space volume is the amount of air in the respiratory system that does not reach the alveoli for gas exchange. Inspiratory capacity is the maximum amount of air that can be inspired after a normal expiration. Functional reserve capacity is the amount of air left in the lungs after a normal expiration. Only tidal volume matches the given definition.
