Which vein is part of the systemic head neck veins?

The anterior jugular vein is considered part of the systemic head and neck veins as it is responsible for draining blood from the superficial regions of the neck and communicating with other veins in the cervical area. This vein runs vertically along the anterior aspect of the neck and plays a role in returning deoxygenated blood to the heart, specifically to the brachiocephalic vein and ultimately to the superior vena cava.

In contrast, the femoral vein is located in the thigh and is part of the lower extremity venous system, while the subclavian vein, although it is associated with the upper body and connects to the jugular veins, is primarily involved in the drainage from the upper limbs. The celiac vein, on the other hand, is involved in the drainage of abdominal organs, such as the stomach and spleen, and does not pertain to the head and neck region. Thus, the anterior jugular vein is the only option specifically linked to the systemic head and neck venous drainage.
