The continuous flow of oxygen is important to birds as they need a lot of energy to fly. Another advantage of the air sacs is that they make birds less heavy! Reptiles The respiratory system of reptiles is similar to that of humans.

WebBirds must be capable of high rates of gas exchange because their oxygen consumption at rest is higher than that of all other vertebrates, including mammals, and it increases many times during flight. The gas volume of the bird lung is small compared with that of mammals, but the lung is connected to voluminous air sacs by a series of tubes, making … 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.
