Which is the main artery that supplies the head and neck with oxygenated blood?

• A. Thoracic
• B. Carpal
• C. Tibial
• D. Common Carotid Artery

Answer: (D)

The main idea here is identifying the artery that delivers oxygen-rich blood to the head and neck. Blood travels from the heart through the aorta and up into the neck, where the common carotid arteries rise on each side. Each common carotid then divides into two branches: the internal carotid, which mainly nourishes the brain and eyes, and the external carotid, which supplies the face, scalp, and neck muscles. Because these arteries are the primary vessels entering the head and neck to provide oxygenated blood, they are the correct choice. Other options don’t fit because they aren’t the main suppliers to the head and neck. The arteries in the thoracic region service the chest area, not the head/neck, and the carpal arteries supply the wrist and hand while the tibial arteries supply the lower leg and foot.
