a duct that carries tears from a gland out to the surface of the eye
lacrimal gland
The nasolacrimal duct carries excess tears into the nasal cavity. This is why you get a runny nose when you cry.
There are several lacrimal glands and they all make tears. The tears are made in response to irritation such as smoke. The gland helps the eye to remove the irritant and dump the tears into the nose. Tears are also produced in response to emotions.
The lacrimal glands produce tears that cleanse and protect the eye by keeping the surface moist and washing away irritants. The tears are then spread across the eye by blinking and other movements of the eyelids.

Tears function as natural barriers because they contain enzymes and proteins that help protect the eyes from infection. They also help wash away irritants and foreign particles, keeping the eyes clean and moisturized. Additionally, the salty nature of tears can create a hostile environment for bacteria and other pathogens.
Tears are produced by the lacrimal glands in response to emotions, irritants, or to moisturize the eyes. When our eyes detect something irritating, a signal is sent to the brain which triggers the release of tears to help protect and lubricate the eyes.
