The lacrimal apparatus is the physiologic system containing the orbital structures for tear production and drainageCassin, B. and Solomon, S. "Dictionary of Eye Terminology". Gainsville, Florida: Triad Publishing Company, 1990.] .
It consists of:

* (a) the lacrimal gland, which secretes the tears, and its excretory ducts, which convey the fluid to the surface of the eye;
* (b) the lacrimal canaliculi, the lacrimal sac, and the nasolacrimal duct, by which the fluid is conveyed into the cavity of the nose.
