What is the role of the ribs in relation to the axial skeleton?

The ribs play a crucial role in protecting the thoracic cavity, which houses vital organs such as the heart and lungs. This protective function is essential for maintaining the integrity of these organs against external forces. Additionally, the ribs aid in the mechanics of breathing; they expand and contract during inhalation and exhalation, allowing the lungs to fill with air and expel it efficiently. The structure of the rib cage creates a safeguard while facilitating respiratory movement, illustrating their dual-purpose function in both protection and respiratory mechanics. While the ribs do contribute to muscle attachment and may indirectly support limb movement through their connection to the sternum and spine, their primary roles strongly emphasize the protection of thoracic organs and their involvement in the respiratory process.
