WebBirds have a light skeletal system and light but powerful musculature which, along with circulatory and respiratory systems capable of very high metabolic rates and oxygen supply, permit the bird to fly. The … WebThe respiratory system of birds is efficient thanks to the use of a thin surface through which gases and blood flow, which allows greater control of body temperature. The diffusion of air for endothermic purposes is more effective insofar as the surface through which blood and gases flow is thinner (Maina, 2002).

WebAlso, birds sometimes fly very high up, where there is very little oxygen in the air. Birds can fly up that high without any help, because of their special lungs.
