Tears come from the lacrimal gland. And it's found in the outer part of the upper eye. When excess tears are produced, they drain into small ducts to the nasal cavity. And if you have too many tears to drain, they'll spill out of your eyes. There's an anatomical reason why crying makes your nose run.
Tears are made primarily by the lacrimal gland, which is anatomically located under the outer one-third of the upper eyelid. With each blink, the eyelid spreads tears over the surface of the eye and pumps excess tears towards ducts in both the upper and lower eyelids.ears are made primarily by the lacrimal gland, which is anatomically located under the outer one-third of the upper eyelid.
