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.
The Lacrimal gland is responsible for the production of tears.  There are two of these glands, located above the outer corners of  each eye. While these glands produce tears â¦ , there is a series of  ducts, canals, and sacs that help transport the tears. A tear gland is located near the eye, in the eyelids; which produce lipid, lacrimal and mucoid layers of the tear film coating, which coats the anterior surface of the c â¦ ornea.
