What are the main veins of the face, head, and neck?

The main veins of the face, head, and neck include the internal and external jugular veins, making the selection correct.

The internal jugular vein is responsible for draining blood from the brain, face, and neck. It runs alongside the carotid arteries and plays a crucial role in returning deoxygenated blood back to the heart. The external jugular vein drains blood from the outer structures of the head, including the jaw, neck, and parts of the face. Understanding the functions and locations of these veins is essential in esthetics practices, as they are significant during procedures involving facial treatments or surgeries.

Other options do not pertain specifically to the veins in the face, head, and neck area. The cephalic and basilic veins primarily drain the arms; the subclavian and brachiocephalic veins are associated with the upper body and thoracic region, while the radial and ulnar veins are found in the forearm and hand. Thus, the internal and external jugular veins are the primary vessels to focus on in this anatomical context.
