Lacrimal apparatus . The eyes are protected and lubricated by tear fluid, or simply tears. The organs of the lacrimal apparatus produce this fluid and drain its excess into the nasal cavity.
The lacrimal apparatus is a system of organs that secrete tear fluid and drain its excess from the eyeball. The lacrimal gland produces fluid, the outflow of which occurs through the lacrimal puncta.
The eyes remain moist due to the continuous production of small amounts of tear fluid by the tear glands. The liquid contains a very strong antibacterial substance lyso-zyme. The main part of the liquid (approximately 1 ml daily for each eye) evaporates. The remaining tear fluid is drained through the nasolacrimal canal into the nasal cavity.
