II. LACRIMAL APPARATUS

The lacrimal system incorporates structures involved in the production and drainage of tears. The secretory component consists of the glands that produce the various ingredients of tear fluid. The nasolacrimal ductules form the excretory element of the system, depositing these secretions into the nose. The tear fluid is distributed over the surface of the eye by the action of blinking.
