== Inferior labial vein ==

The inferior labial vein is a blood vessel that is part of the venous system of the face. It is responsible for draining blood from the lower lip and is a component of the facial vein network.

Anatomy

The inferior labial vein originates from the venous plexus of the lower lip. It runs along the inner surface of the lower lip and eventually drains into the facial vein. The facial vein then continues its course to join the internal jugular vein, which is a major vein in the neck.

Function

The primary function of the inferior labial vein is to collect deoxygenated blood from the tissues of the lower lip and transport it back to the heart. This process is essential for maintaining proper circulation and oxygenation of the tissues.

Clinical Significance

The inferior labial vein can be involved in various medical conditions, such as venous insufficiency, varicose veins, and hematoma formation. It is also a consideration during surgical procedures involving the lower lip, such as lip augmentation or reconstructive surgery.
