The thorax is the skeletal structure that consists of the rib cage, sternum, and thoracic vertebrae, and is specifically designed to protect vital internal organs, including the heart and lungs. Its bony framework forms a protective cavity that houses these organs, which are critical for respiratory and circulatory functions. The ribs articulate with the spine and stretch around the sides of the body, creating a shield that helps prevent injury from external forces.

While the spine provides support and protection for the spinal cord, and the pelvis encases the lower organs and supports the torso, neither of these structures offers the same level of protection for the heart and lungs as the thorax does. The skull, on the other hand, protects the brain and sensory organs but does not contribute to the protection of the thoracic organs. Therefore, the thorax is uniquely suited to serve the protective function essential for maintaining the safety and integrity of the heart, lungs, and other internal organs located in that area.
