Description
Branching from the lateral aspects of the face, from a common point just inferior to the lobe of the ear, are a series of lymphatic vessels that drain the tissues of the face. These vessels have a series of nodes present along their length, usually grouped by their location. These vessels primarily drain the superficial tissues of the face, with a small number of deep vessels collecting lymphatic fluid from the tongue, oral, and nasal cavities.
Blockage of the vessels is uncommon, the lymphatic system most often gets blocked at the nodes. However edema can occur in the drainage territory if a blockage does occur.

Lymph Vessel
The lymph vessels are blind-ending capillaries which have gaps in their endothelial walls enabling protein molecules to move through easily.
