Ribs

August 2017


Definition

The ribs refer to the aggregate bones that constitute, along with the vertebrae and sternum, the ribcage. In humans there are 12 pairs of ribs, i.e. 24 bones that are flat, elongated, and curved. Each rib is attached at the back to two vertebrae, and for some, at the front to the sternum cartilage. The latter are the 7 pairs of sternal ribs. The ribs protect vital organs (heart and lungs) and allow for easier breathing by accompanying the movements of inhalation / exhalation.
