ARCH OF AORTA Meaning and
Definition
-
The arch of the aorta is a curved section of the aorta, the largest artery in the body, that arises from the upper part of the left ventricle of the heart. Located at the base of the heart, the arch of the aorta curves upwards, backwards, and then downwards to form an arch-like shape. It acts as a major conduit for oxygenated blood to be distributed to the body.
The arch of the aorta is comprised of several important anatomical structures, including three major branches that provide blood supply to various organs. These branches are the brachiocephalic artery, the left common carotid artery, and the left subclavian artery.
The brachiocephalic artery divides into the right common carotid artery and the right subclavian artery. The common carotid arteries supply oxygenated blood to the head and neck region, while the subclavian arteries provide blood to the upper limbs. The left common carotid artery arises directly from the arch of the aorta and supplies blood to the left side of the head and neck.
The arch of the aorta serves as a crucial connection between the left ventricle of the heart and the rest of the body. It plays a vital role in maintaining proper blood circulation and serving as a conduit for the delivery of oxygen and nutrients to various organs and tissues.
