The ribs are flat, thin bones that, together with the sternum, make up the ribcage. The ribs provide protection for vital organs in the upper body, including the heart and lungs. The ribs also help to protect major vessels in the upper body. There are twelve pairs of ribs, accounting for 24 total rib bones.
