Identify the vessel that conducts blood from the left ventricle?

The Aorta (the aortic arch)

The left ventricle of the human body contains oxygenated blood. This oxygenated blood is pumped to all parts of the body except the lungs. Hence the left ventricle which has a thick cardiac wall pumps blood through aorta, the main artery, which is the only blood vessel that arises from the left ventricle.
