Which region drains into the external jugular vein?

• A. The more superficial portions of the head, scalp, and cranial regions
• B. Deep facial structures
• C. Limbs
• D. Abdominal organs

Answer: (A)

The external jugular vein collects blood from the superficial tissues of the head and neck. It runs superficially across the side of the neck and drains into the subclavian vein. So, the region that drains into it is the more superficial portions of the head, scalp, and cranial areas. Deeper facial structures drain into the internal jugular system through the facial veins and plexuses, the limbs feed into the subclavian/axillary veins, and abdominal organs drain via the portal or systemic venous systems—none of which primarily feed the external jugular.
