Which artery supplies blood to the head and brain?

• A. Carotid Artery
• B. Aorta
• C. Pulmonary Artery
• D. Femoral Artery

Answer: (A)

Carotid arteries deliver blood to the head and brain. Each side has a common carotid artery that splits into the internal carotid and external carotid arteries. The internal carotid travels into the skull and supplies the brain with oxygen-rich blood, while the external carotid supplies the face and scalp. This makes the carotid arteries the primary vessels for perfusing the head and brain. The aorta distributes blood to the whole body, the pulmonary artery sends blood to the lungs, and the femoral artery serves the leg, not the brain.
