Tear Drainage System
The lacrimal gland produces tears. These tears drain through two small openings called the upper and lower puncta, then through the canaliculus and into the lacrimal sac. They drop into the nasolacrimal duct and drain into the back of the nose and throat. Learn more about the tear drainage system at http://www.geteyesmart.org.
