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. WebNov 13, 2015 · Birds are capable of high rates of gas exchange because of the special construction of their lungs, and additional breathing organs, a complex series of air sacs. Connecting tubes join the lungs to these air sacs, increasing a bird's respiratory capacity to about twice that of any mammal of comparable size.

Birds can fly up that high without any help, because of their special lungs. The bird's respiratory system takes up 20% of a birds's volume (our respiratory system takes up only 5% of our volume). Birds breath much more rapidly than humans do.

WebNov 13, 2013 · Why is the respiratory system of a bird more efficient than the human respiratory system? A.A bird lung contains multiple alveoli, which increases the amount of surface area available for gas exchange. B.The human respiratory system ends in small parabronchi, which reduce the amount of surface area available for gas exchange. WebIn birds the lungs expand very little because the air goes through them into the air sacs and back through the lungs on expiration. Thus not only can a greater volume of air pass through the lungs, but since it passes through twice, gas exchange is more efficient. In addition, birds’ lungs have more capillaries/area than mammals.
