WebAvian lungs are relatively compact, with a bird's lungs being approximately 50% as large as the lung of a mammal of a similar size. The lungs are unlobed and do not have the capacity to expand due to the close arrangement between the finite gas exchange structures, i.e.the air capillaries and blood capillaries and scanty connective tissue. WebJan 29, 2024 · Answer: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. This also means that toxins in the air are also transferred more efficiently.
