Detailed explanation-1: -The rib cage surrounds the lungs and the heart, serving as an important means of bony protection for these vital organs.In total, the rib cage consists of the 12 thoracic vertebrae and the 24 ribs, in addition to the sternum.
Detailed explanation-2: -The ribs protect the vital organs of the torso, particularly the heart and lungs, by wrapping around from the thoracic vertebrae of the spine in the back to the sternum in the front.
Detailed explanation-3: -These findings thus confirm that the ribs play a critical role in the act of breathing by converting intercostal muscle shortening into lung volume expansion. In addition, they carry the compression that is required to balance the pressure difference across the chest wall.
