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.
1 Tears have three main components: The lachrymal gland produces a watery component. â¦ 2  glands in our eyelids produce an oily component, while other cells produce a mucus. 3  These mix together to create a film which covers the white of the eye and the cornea.  When we blink, the film is wiped across the eye by the eyelids.
