Branches of Aorta

Aorta is the largest artery in the body. It originates from the Left Ventricle.

What Does The Aorta Do In The Heart?
It carries the oxygenated (pure) blood to various parts of body through its numerous branches. At the origin, the flow of blood from the left ventricle to aorta is controlled by Aortic Valve.

Normal aorta is 2.5-3.0 cm in diameter at the origin. The diameter gradually comes down as it gives away branches. Before bifurcating in the abdomen it is about 1.5-2.0 cm.
