Which artery supplies blood to the head?

• A. Renal
• B. Iliac
• C. Carotid
• D. Mesenteric

Answer: (C)

The head is supplied by the carotid arteries. These arteries rise from the aorta (or from the first branches like the brachiocephalic trunk) and split into internal and external branches. The internal carotid vessels deliver blood to the brain and some structures of the head, while the external carotid arteries supply the face, scalp, and other head tissues. The other arteries listed have roles in other regions: renal arteries go to the kidneys, mesenteric arteries to the intestines, and iliac arteries to the pelvis and hind limbs. So the carotid vessels are the ones that serve the head.
