In simple organisms, such as cnidarians and flatworms, every cell in the body is close to the external … 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. rawls testing center stats
