In birds exchange of gases occurs
Web‘ In the avian lung, the gas exchange occurs in the walls of microscopic tubules, called ‘air capillaries. ‘ The respiratory system of birds is more efficient than that of mammals, transferring more oxygen with each breath. Why is gas exchange in birds so efficient? This exchange is very efficient in birds for a number of reasons. WebGas exchange in reptiles still occurs in alveoli, but reptiles do not possess a diaphragm, therefore ventilation occurs via a change in the volume of the body cavity which is …
