Inhaled air passes through the primary bronchus, and most enters the posterior air sacs as well as the lungs. During this passage, air that was in the posterior air sacs moves through the lungs air capillaries so that exchange takes place. During exhalation, the air in the posterior air sacs passes through the lung en route to the external environment. Again exchange goes on during exhalation.
