In crocodilians, the diaphragmaticus muscle mass, that's analogous on the diaphragm in mammals, attaches the lungs on the liver and pelvis. For the duration of inhalation, the exterior intercostal muscles develop the ribs, letting the animal to absorb far more air, although the ischiopubis muscle will cause the hips to swing downwards and drive the belly outward, though the diaphragmaticus pulls the liver back again.
