Which skeletal structure protects vital organs such as the heart and lungs?

The thorax is the skeletal structure that protects vital organs such as the heart and lungs. It is formed by the rib cage, which includes the ribs, sternum, and thoracic vertebrae. This structure encases the thoracic cavity, providing a protective barrier around these critical organs, allowing for safe movement during respiration while also preventing potential injury from external forces.

The ribs are specifically designed to expand and contract as we breathe, which is essential for the proper functioning of the lungs. The sternum acts as a front shield, and the vertebrae at the back provide additional support and protection. Together, these components create a robust and flexible enclosure that is vital for respiratory function and the overall safety of the cardiovascular system.
