What's the largest artery in the body?

The largest artery is the aorta because it serves as the main highway for blood leaving the heart to supply the entire body. It starts from the left ventricle, arches and descends to distribute blood through its many branches to every organ. Its diameter is larger than the other arteries listed, designed to carry the entire cardiac output and to help dampen the surge of blood with each heartbeat through its elastic walls. In comparison, the carotid arteries supply the head and neck and are smaller; the pulmonary artery carries blood to the lungs as part of the separate low‑pressure circuit; and the femoral artery runs down the leg but isn’t as wide as the aorta.
