Your body produces tears constantly to keep the eyes moist, lubricated, and healthy. This is accomplished by the lacrimal gland and other small glands located inside your eyelids and on the clear tissue (conjunctiva) covering the white of the eye. When produced, the tears normally drain through two small openings called puncta that are located in the upper and lower eyelids at the corners nearest to your nose. The tears then pass through a passage called the canaliculus into the lacrimal sac. They then exit through the nasolacrimal duct into the back of your nose and throat. This is the reason that your nose runs when you cry.
