Facial vein
Facial Vein
The Facial Vein (pronunciation: /ˈfeɪʃəl veɪn/) is a significant vein in the human anatomy that drains blood from the facial structures.
Etymology
The term "Facial Vein" is derived from the Latin words 'facies' meaning face and 'vena' meaning vein.
Structure
The Facial Vein begins at the side of the root of the nose and is a continuation of the angular vein where the supratrochlear vein merges with the supraorbital vein. It runs obliquely downward and backward, beneath the zygomaticus and quadratus labii superioris, and then descends nearly vertically down the face, alongside the facial artery.
Function
The primary function of the Facial Vein is to drain blood from the facial structures and transport it back to the heart. It is connected to the internal jugular vein, which carries this deoxygenated blood to the heart.
