In vertebrate anatomy, ribs are the long curved bones which form the rib cage. In most tetrapods, ribs surround the chest, enabling the lungs to expand and thus facilitate breathing by expanding the chest cavity. They serve to protect the lungs, heart, and other internal organs of the thorax. In some animals, especially snakes, ribs may provide support and protection for the entire body.
Diaphragm seprates chest cavity from abdominal cavity
The four main abdominal muscle groups that combine to completely cover the internal organs include: transversus abdominis – the deepest muscle layer. rectus abdominis – slung between the ribs and the pubic bone at the front of the pelvis. external oblique muscles – these are on each side of the rectus abdominis.
