lacrimal

[lak´rĭ-mal]

pertaining to tears.

lacrimal apparatus a group of organs concerned with the production and drainage of tears; it is a protective device that helps keep the eye moist and free of dust and other irritating particles. The lacrimal gland, which secretes tears, lies over the upper, outer corner of the eye; its excretory ducts branch downward toward the eyeball. A constant stream of tears washes down over the front of the eye and is drained off through two small openings located in the inner corner of the eye. Through these openings the tears pass into the lacrimal canaliculus, then through the lacrimal sac into the nasolacrimal duct and finally into the nasal cavity.
