Heart and Aorta ANATOMY OF THE AORTA | Page 2

It originates from the Left Ventricle. 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 2.5-3.0cm in diameter at the origin. The diameter gradually comes down as it gives away branches. Before bifurcating in the abdomen it is about 1.5-2.0cm. Copyright ⓒ 2017​ Heart and Aorta​ . All rights reserved.
