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 controlled by contraction of intercostal muscles in all reptiles except turtles. In turtles, contraction of specific pairs of flank muscles governs inspiration or expiration.

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. WebBut in birds these processes of gas exchange and ventilation happen in two different organs. They have relatively small lungs so that the organs needed for both gas exchange and ventilation can function in such a small space. The lungs preform the gas exchange and nine different air sacs within the body preform ventilation. the painter tonyWebRespiratory gas exchange is conducted through the thin, gas-permeable skin and the gills.
