Which arteries are responsible for supplying blood to the head?

The common carotid arteries play a crucial role in supplying blood to the head. They are large blood vessels located on either side of the neck and divide into the internal and external carotid arteries. The internal carotid arteries provide blood to the brain, while the external carotid arteries supply blood to the face and neck. This bifurcation and specialization of the carotid arteries ensure that the head, which includes critical structures like the brain, face, and scalp, receives an adequate supply of oxygenated blood necessary for proper functioning.

Subclavian arteries primarily supply blood to the upper limbs and portions of the thorax, while radial arteries are a continuation of the brachial artery in the forearm, serving the hand. The aorta branches are responsible for distributing blood throughout the body but are not specifically designated for head supply. Thus, while each of these arteries has its significant roles, the common carotid arteries are the essential vessels focused on delivering blood specifically to the head.
