Descending Aorta

The descending aorta is the part of the aorta, the largest artery in the body, that runs down through the chest and the abdomen. The descending aorta starts after the arch of the aorta and ends by splitting into two great arteries that go to the legs. The descending aorta, by convention, is subdivided into the thoracic aorta and the abdominal aorta. The thoracic aorta, the part of the aorta that runs from the arch of the aorta to the diaphragm, gives off numerous branches that supply oxygenated blood to the chest cage and the organs within the chest.
