he largest artery in the body, the aorta arises from the left
ventricle of the heart, goes up (ascends) a little ways, bends over
(arches), then goes down (descends) through the chest and through the
abdomen to where ends by dividing into two arteries called the common
iliac arteries that go to the legs.
Anatomically, the aorta is traditionally divided into the ascending aorta, the aortic
arch, and the descending aorta. The descending aorta is, in turn, subdivided into the
thoracic aorta (that descends within the chest) and the abdominal aorta (that descends
within the belly).
The aorta gives off branches that go to the head and neck, the arms, the major organs
in the chest and abdomen, and the legs. It serves to supply them all with oxygenated
blood. The aorta is the central conduit from the heart to the body.
