Explanation

Human beings have 12 pairs of ribs, totaling 24 ribs in the body. These ribs protect vital organs like the heart and lungs while allowing for the expansion and contraction necessary for breathing. The first seven pairs are called "true ribs" because they connect directly to the sternum, the next three pairs are "false ribs" that attach indirectly, and the last two pairs are "floating ribs" that don't attach to the sternum at all.
