The Aorta Artery Further Subdivides Into Other BranchesThe aorta artery is the largest artery and it is responsible for sending oxygenated blood to every single tissue of the body. This artery further subdivides into other sections. 1. The ascending aorta starts at the left ventricle and it ends at the start of the aortic branch. This is where the two main coronary arteries originate from which supply oxygenated blood to the heart muscle. 2. The aortic arch is the second section of the aorta and this is where the brachiocephalic trunk, the left common carotid artery, and the left subclavian artery originate from. The right subclavian artery and the right common carotid artery originate from the brachiocephalic trunk. 3. The descending aorta further subdivides into the thoracic aorta and the abdominal aorta. A. The thoracic aorta branches out into many small arteries that supply blood to the chest cavity and organs that are within the cavity. B. The abdominal aorta starts at the diaphragm and provides oxygenated blood to the abdominal cavity and its organs.  Normal Aorta Return from aorta artery to the heart page
