The rib is important because it is a key component of the rib cage, which protects vital organs and facilitates breathing. The rib cage consists of 12 pairs of ribs and the sternum.
Protection and Breathing
The primary functions of the rib cage, and therefore the ribs, are:
- Protection: The rib cage protects the heart and lungs from injury. The ribs' curved shape and arrangement provide a sturdy barrier against external forces.
- Facilitating Breathing: The ribs, along with the muscles attached to them, play a crucial role in the mechanics of breathing. They expand and contract to allow air to enter and exit the lungs.
The rib cage, made up of the ribs and sternum, is vital for maintaining the health and function of the respiratory and cardiovascular systems.
