It is the first branch of the aortic arch.[3] Soon after it emerges, the brachiocephalic artery divides into the right common carotid artery and the right subclavian artery.[4]
There is no brachiocephalic artery for the left side of the body. The left common carotid artery and the left subclavian artery come directly off the aortic arch. Despite this, there are two brachiocephalic veins.[5]
