What is "rib"?

The rib refers to a part of the body that forms part of the bony framework of the chest, known as the ribcage or thoracic cage. Humans have 12 pairs of ribs that attach to the spine at the back and curve around to the front, connecting to the sternum (breastbone) or other ribs via cartilage. Ribs provide protection to vital organs within the chest cavity, such as the heart and lungs. They also play a role in facilitating breathing by expanding and contracting with the movement of the diaphragm. Additionally, ribs contribute to the overall stability of the torso and serve as attachment points for various muscles involved in breathing and posture.
