Tears drain from the puncta into which structures?

Explanation:
Tears leave the eye through the tiny openings called puncta on the eyelids, and then they travel through the lacrimal canaliculi to the lacrimal sac, down the nasolacrimal duct, and finally into the nasal cavity. This drainage route explains why crying can make your nose run. Tears aren’t drained by the lacrimal gland (which makes tears), nor do they pass through the pupil or into the vitreous inside the eye.
