The common carotid artery is a blood vessel. There is a left and right common carotid artery. The left common carotid branches directly off of the aortic arch, and the right common carotid branches off of the right innominate (brachiocephalic) artery. The common carotid artery later bifurcates into the internal and external carotid arteries. The external carotid supplying blood to the face, and the internal carotid supplying blood to the brain.
