Most humans have 24 ribs, arranged in 12 pairs. This is the standard anatomy for both males and females. However, there are some exceptions, such as people born with specific genetic anomalies, which can result in having either more ribs (supernumerary ribs) or fewer ribs (agenesis of ribs).
The rib cage is essential for protecting the lungs and heart, two of the most vital organs in the body. The ribs also help with breathing, as they move with the lungs during inhalation and exhalation.
While it's a common misconception, men and women do not have different numbers of ribs. The rib cage is the same structure in both sexes, and the number of ribs is primarily determined by genetics.
