Overview
The thorax is also called the chest and contains the main organs of respiration and circulation. The heart through its main artery, the aorta, pumps oxygenated blood to all parts of the body. The lungs provide oxygen to the cells of the body and eliminate carbon dioxide. Together these organs sustain some of the most critical life functions of the body.
