Aorta. Coloured 3D computed tomography (CT) angiogram of the aorta of a 54 year old patient. The aorta is the body's main artery. It carries blood from the heart (upper centre) to the rest of the body. At centre left and right are the kidneys, with the renal arteries seen branching from the aorta. At lower centre the aorta branches into the iliac arteries, which serve the legs. There are small fatty plaques (white, atherosclerosis) in the lower aorta and iliac arteries.
