WebFeb 3, 2024 · A more efficient system. Birds employ a more efficient system, one in which thin-walled air sacs are connected to the lungs. As shown in the illustration of the cardinal, the air sacs fill the body cavity. They are not involved directly in gas exchange but function as bellows to direct airflow through the lungs in one direction, from back to front. WebIn mammalian lungs, the exchange of oxygen and carbon dioxide occurs in microscopic sacs in the lungs, called 'alveoli.'. In the avian lung, the gas exchange occurs in the walls of microscopic tubules, called 'air capillaries.'.
