Best Answer

The subclavian arteries carry blood to the arms. The branching from the aorta on the right side of the body is as follows :

Aorta- brachiocephalic- subclavian- axillary (located in your upper arm). From those, you have lots of branches.

In the left side, the aortic branching is slightly different.

Aorta-left subclavian (directly)-axillary

The aorta has a third branch on the arch to the left common carotid, which is the reason that the left side doesn't have the brachiocephalic branch that the right side does. The brachiocephalic branch is just the right subclavian and common carotid running together before a branching point.

Hope this helps!

What portions of the body are supplied by blood from the branches at the top of the aortic arch?

The three main branches at the top of the aortic arch are the brachiocephalic artery, left common carotid artery, and left subclavian artery. The brachiocephalic artery supplies blood to the right arm and the right side of the head and neck. While the left common carotid artery supplies blood to the left side of the head and neck, the left subclavian artery is responsible for blood supply to the left arm.
