Jugular vein - Definition

February 2017


Definition

The jugular veins are blood vessels that carry deoxygenated blood from the head down to the heart. The different jugular veins are the two internal jugular veins, which are the largest; two external jugular veins; two posterior external jugular veins; and two anterior jugular veins, one of each running up each side of the neck. These veins perform drainage of blood from the brain and face, transporting it down to the subclavian veins. The internal jugular veins are large veins that can be impaired by lesions that cause massive hemorrhages.
