Explanation

Aortic arch gives 3 branches.That is, on the right side of the body gives rise to brachiocephalic trunk and on the left side gives rise to left common carotid artery and left subclavian artery. The brachiocephalic artery is divided into right common carotid artery and right subclavian artery.
