Aorta

Aorta: Aorta is the largest blood vessel carrying oxygenated blood from the heart to the whole body. It extends from the left ventricle through the chest to lower part of the abdomen (tummy). Its branches supply blood to all parts of the body. Aortic valve, a trileaflet valve prevents backflow of blood from aorta to left ventricle when the latter relaxes after contraction.
