exploratory volume: volume of air that can be exchanged during a maximum forced expiration beyond tidal volume
residual volume: volume of air enters remains the lungs after maximal expiration average is 1,200 mb cannot be measured
-
total lung capacity: total volume of air the lungs can hold vct + RV varies with age gender and body size
