Left Common Carotid Artery

Springing directly from the aorta, the left common carotid artery arises from the highest part of the aortic arch, between the brachiocephalic artery and the left subclavian artery. The left common carotid artery has a substantial presence in the thoracic region, traveling upward through the superior mediastinum to the level of the left sternoclavicular joint, where it is continuous with the cervical portion. The left common carotid artery is an artery that supplies the head and neck with oxygenated blood. In the neck, it divides to form the external and internal carotid arteries.
