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.
Function: The Tear Apparatus. Tears are produced by the lacrimal (tear) glands, which are situated above each eyeball. The glands continually secrete a small amount of salty fluid that is distributed over the surface of the eyes through the action of blinking and drain into the nose. Tears form a protective film that lubricates the eye and flushes out any dust and dirt. They also contain an antibacterial ingredient. Tear production increases when you cry or if the eye is irritated by a chemical or foreign particle.
