Final answer:
The correct answer to the question about the vessels branching from the aortic arch is option a) Brachiocephalic artery, left common carotid artery, left subclavian artery. These vessels are elastic arteries and involved in supplying blood to the head, neck, upper limb, and thoracic wall.
Step-by-step explanation:
The three vessels that branch out from the aortic arch, listed from right to left (which corresponds approximately to anterior to posterior perspective) are: a) Brachiocephalic artery, left common carotid artery, and left subclavian artery. The brachiocephalic artery is the first and largest branch located on the right side of the body and it further branches out into the right subclavian artery and the right common carotid artery. Next is the left common carotid artery that supplies blood to the left side of the head and neck. Eventually, the left subclavian artery, which arises independently from the aortic arch, supplies blood to the left arm, part of the thoracic region, and contributes to cerebral circulation via its branches.
