How many pairs of ribs are typically found in the human body?

The typical number of pairs of ribs in the human body is 12. This anatomical structure consists of 24 individual ribs, forming a protective cage around the heart and lungs and playing a crucial role in the respiratory system. The 12 pairs include seven pairs of true ribs, which directly attach to the breastbone (sternum), followed by three pairs of false ribs, which are indirectly connected, and then two pairs of floating ribs that do not have a front attachment. This anatomical knowledge is essential for understanding how the skeletal system functions and how it protects vital organs. The other choices do not accurately reflect the total number of rib pairs present in a standard adult human skeleton.
