We have tear ducts to lubricate and protect our eyes from dust and other particles. The ducts are under the upper eyelids and produce a salty liquid—a tear-–-that gets spread throughout the eye after each blink. Animals too have the ability to produce tears, but not necessarily for the same reasons that we humans produce them.
Three types of tears are generated by the human eye. Basal tears protect the eye and keep it moist. Reflex tears flush out the eye when it becomes irritated. And emotional tears flow in response to sadness, distress, or physical pain.

Basal tears are released regularly to keep your eyes lubricated. Reflex tears are those produced when irritants bother our eyes. Emotional tears are produced in the grip of extreme emotions: sadness, anger, and sometimes even laughter. Furthermore, we tend to produce emotional tears when we get injured, and some researchers suggest that the body doesn't really differentiate between emotional and physical pain, even if the mind can.
