Best Answers

At the chest, many rib bones connect to the sternum via costal cartilage, segments of hyaline cartilage that allow the rib cage to expand during respiration. Although fixed into place, these ribs do allow for some outward movement, and this helps stabilize the chest during inhalation and exhalation. read more

A typical human rib cage consists of 24 ribs, the sternum (with xiphoid process), costal cartilages, and the 12 thoracic vertebrae. Together with the skin and associated fascia and muscles, the rib cage makes up the thoracic wall and provides attachments for the muscles of the neck, thorax, upper abdomen, and back. read more

The rib cage helps push air out of the lungs as well. Muscles lining the rib cage help move the rib cage up upon inhalation, so the lungs can expand. During exhalation, the muscles and the lungs relax, allowing the weight of the rib cage to push out carbon dioxide air through the mouth and nose. read more
