Q. What structure of the eye produces tears?

Lachrymal gland, which is a part of larger lachrymal apparatus, produces tears that flow over anterior surface of the eye. Most of this fluid evaporates though excess amounts are collected in small ducts in the corner of the eye. Tears lubricate and cleanse the eye. Additionally, tears contain lysozyme, an enzyme which is capable of destroying certain kinds of bacteria and helps fight eye infections.
