All through inhalation, the exterior intercostal muscles develop the ribs, making it possible for the animal to absorb a lot more air, even though the ischiopubis muscle mass will cause the hips to swing downwards and press the belly outward, although the diaphragmaticus pulls the liver back. When exhaling, the internal intercostal muscles force the ribs inwards when the rectus abdominis pulls the hips and liver forwards as well as belly inward.
