Bird gas exchange
WebAbstract. Lungs of birds are homologous to lungs of mammals, and both are phylogenetically derived from those of their reptilian ancestors. There exist, however, fundamental differences between avian and mammalian lungs in anatomical design, leading to differences in respiratory gas flow pattern and in gas exchange function. WebNov 12, 2024 · Luckily, birds have developed some very neat respiratory features to meet this high oxygen requirement. In a bird’s gas exchange region, the blood and air capillaries are arranged crosswise over each other in the shape of an “x,” with blood moving at an angle in relation to the fresh air in the air capillaries.
