The external jugular vein is a prominent superficial vein in the neck that receives blood from the scalp and face. It travels down the neck, parallel to the sternocleidomastoid muscle, and eventually drains into the subclavian vein. It plays a crucial role in draining deoxygenated blood and waste products from the head and neck region, contributing to the overall circulation and venous return of the body.
