The common carotid arteries split into two main branches â the internal carotid artery and the external carotid artery. The external carotid artery is the only division of the common carotid that gives branches to the neck region and supplies the external structures of the head and face.
The carotid arteries are major blood vessels in the neck that supply blood to the brain, neck, and face. There are two carotid arteries, one on the right and one on the left. 1  The internal carotid artery supplies blood to the brain.  The external carotid artery supplies blood to the face and neck.
