The lacrimal apparatus is the physiologic system containing the orbital structures for tear production and drainage.
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.
