WebAquatic arthropods generally possess some form of gills in which gas exchange takes place by diffusing through the exoskeleton.Others may breathe atmospheric air while remaining submerged, via breathing tubes or trapped air bubbles, though some aquatic insects may remain submerged indefinitely and respire using a plastron.A number of insects have an … 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.
WebOct 26, 2024 · lungs. Similar to mammals, birds have lungs, which are organs specialized for gas exchange. Oxygenated air, taken in during inhalation, diffuses across the surface of the lungs into the bloodstream, and carbon dioxide diffuses from the blood into the lungs, and is then expelled during exhalation. WebBirds have large air spaces called air sacs in their lungs. When a bird inhales, its rib cage spreads apart and a partial vacuum is created in the lungs. Air rushes into the lungs and then into the air sacs, where most of the gas exchange occurs. This system is birds’ adaptation to the rigors of flight and their extensive metabolic demands.
