The aorta is the largest and main artery in the body, it comes from the left ventricle of the heart, goes up   arches (like an umbrella handle) then goes down through the chest and through the abdomen and into the pelvis where it divides into two arteries that go down each leg. It branches out to various parts of the body, (arms, head, and major organs) supplying oxygenated blood
