The rib cage is a bony structure that protects vital organs in the chest, such as the heart and lungs. It is made up of 12 pairs of ribs that curve around the body, connecting to the spine at the back and to the breastbone, or sternum, at the front. This cage-like formation allows for flexibility and movement while providing essential support. In addition to protection, the rib cage plays a crucial role in breathing. When we inhale, the ribs expand, creating more space in the chest cavity for the lungs to fill with air. This process is vital for delivering oxygen to the body and removing carbon dioxide, ensuring our overall health and well-being.
