Aortic Disease in Neurology

Abstract

Sinisa Franjic

The aorta is the largest artery in the body that comes out of the left ventricle of the heart. Oxygen-rich blood enters the aorta with each contraction of the left ventricle and reaches all tissues and organs in the body through its small branches. The walls of the aorta consist of three layers that are made of different tissues: an inner thin layer, a middle thicker elastic layer and a thin outer layer. The walls of the aorta must be flexible enough to accommodate all the blood that is ejected from the left ventricle during each contraction. Elastic fibers are especially dense in the part of the ascending aorta where the blood pressure is the highest.
