The aortic arch is the area in which the aorta bends in order to descend into the body. It also gives way to three major blood vessels. Thus, the "functions" of the aortic arch are:

  1. To bend back the main vessel in order to reach the part of the body below the heart itself;
  2. To give off 3 major arteries: the brachiocephalic artery, left common carotid artery, left subclavian artery.
