What's the use of convex ribs

1. Keep the shape of the chest: The protruding ribs keep the chest in a stable shape and protect internal organs, such as the heart and lungs.

2, participate in the breathing process: rib protrusion and rib connection, participate in the breathing process through muscle contraction and relaxation. When muscles contract, the ribs protrude and expand outward, which increases the volume of the chest cavity and allows air to enter the lungs. When the muscles relax, the ribs protrude outward and contract inward, so that the volume of the chest cavity is reduced and the air is exhausted.

3. Protecting internal organs: The ribs protrude to form the skeleton of the chest, which can protect important internal organs such as the heart, lungs and spleen and reduce the damage of external shocks to these organs.

4. Provide muscle attachment point: costal process is the connecting part between rib and thoracic vertebra. Muscles can provide strength and support by attaching to ribs, and participate in various sports and sports.
