Alveolar air volume - ANSWERamount of air that reaches alveoli for gas exchange (approx. 350 ml. For adult male) Tidal volume minus dead space Dead air space - ANSWERanatomic dead space are structures that hold air but but can't participate in gas exchange. Physiologic dead space are alveoli or capillaries destroyed by disease Expiratory reserve volume - ANSWERamount of gas that can be forcefully expired at the end of a normal expiration Inspiratory reserve volume - ANSWERamount of gas...
