Aorta

Aorta

Begins at the aortic root emerging from the left ventricle. The ascending aorta gives off coronary arteries, the aortic arch gives off brachiocephalic, left common carotid, and left subclavian arteries. The descending aorta passes through the thorax and abdomen, bifurcating into common iliac arteries at L4.

Type Vessel
Body System Cardiovascular
Body Region Heart Region
Latin Name Aorta
FMA ID 3734

Function

The largest artery in the body, carrying oxygenated blood from the left ventricle to distribute to all body tissues via its branches. Maintains blood pressure through elastic recoil of its walls (Windkessel effect).

Clinical Significance

Aortic aneurysm (dilation) can rupture, causing fatal hemorrhage. Aortic dissection is a life-threatening tear in the aortic wall. Atherosclerosis commonly affects the aorta. Coarctation of the aorta is a congenital narrowing.
