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 wash down from the glands and over your eyes. Some of the tears drain out of your eyes through tear ducts, or lacrimal ducts. These ducts are tiny tubes that run between your eyes and your nose. Each tear duct is like a tiny bathtub drain. When the tears fill up your eyes, they drain out through the tear ducts.
