Which artery is the primary source of blood supply to the head, face, and neck?

The carotid artery is recognized as the primary source of blood supply to the head, face, and neck. This artery branches off from the aorta and divides into the internal and external carotid arteries, which serve distinct regions. The internal carotid artery primarily supplies blood to the brain, while the external carotid artery supplies the face and neck muscles, as well as the skin and other tissues in those areas.

Understanding the role of the carotid artery is critical for estheticians, as many facial and neck treatments involve understanding this vascular supply to avoid complications during procedures. Knowledge of this blood supply is essential when considering the effects of treatments such as facial massage, extractions, or other procedures that may influence circulation or healing in these regions.

The other arteries mentioned, while significant in their own right, do not serve as the primary source for supplying blood specifically to the head, face, and neck. The subclavian artery mainly supplies blood to the upper limbs and some other structures but does not directly supply the head and face. The brachial artery is involved in supplying blood to the arm, while the aorta is the major artery that branches out to various parts of the body but is not focused on the head, face, and
