Right Common Carotid Artery

Tuesday, May 10, 2011

The right common carotid artery originates from the brachiocephalic trunk, which in turn arises from the arch of the aorta. Running upward into the right side of the neck, it divides into the external and internal carotid arteries. The right common carotid artery supplies oxygenated blood to the neck and head, as does the left common carotid artery. The internal carotid artery, which branches off from the right common carotid, supplies oxygenated blood to the brain and eyes; external carotid artery branches off to supply oxygenated blood to the throat, neck glands, tongue, face, mouth, ear, scalp and dura mater of the meninges.
