Full Arch of Aorta Description
[Continued from above] . . .
Three major arteries branch off from the superior arterial wall of the aortic arch to supply blood to the tissues of the superior regions of the body: the brachiocephalic trunk, left common carotid artery, and left subclavian artery. The brachiocephalic trunk is the first artery to arise from the aortic arch, carrying blood to the right arm and the right side of the head and neck. Next to branch from the aorta is the left common carotid artery that supplies blood to the left side of the head and neck. Finally, the left subclavian artery arises from the aortic arch and supplies blood to the left arm.
