What Is the Function of the Aortic Arch?


The aortic arch gives rise to three major arteries: the brachiocephalic trunk, the left subclavian, and the left common carotid. The function of the aortic arch is to supply oxygenated blood to these arteries, which in turn supply the head and brain, and left upper extremity. Aortic arch may also refer to any of several arterial channels around the embryonic pharynx.
