What are the primary arteries that supply blood to the head, face, and neck?

Common carotids
Subclavians
Brachial arteries
Femoral arteries

The correct answer is: Common carotids

The common carotids are the primary arteries responsible for supplying blood to the head, face, and neck. They branch from the aorta, with the right common carotid arising from the brachiocephalic trunk and the left common carotid stemming directly from the aortic arch. Each common carotid artery ascends the neck and bifurcates into the internal and external carotid arteries, which supply different regions: the internal carotid primarily supplies the brain, while the external carotid provides blood to the face and neck. In contrast, the subclavians originate from the aorta (or the brachiocephalic trunk) and primarily supply the arms and parts of the thorax, making them less relevant to the head and neck's vascularization. The brachial arteries are located in the upper arm and are vital for supplying blood to the arm but do not have a direct role in supplying blood to the head and neck. The femoral arteries are located in the thighs and primarily supply blood to the lower limbs, having no connection to the supply of the head, face, and neck regions.
