Tears:

Tears are transparent liquids released by the lacrimal glands (tear glands) present in all terrestrial animals' eyes.

Functions:

  1. They help the immune system by lubricating the eyes, eliminating irritants, and assisting the eyes.
  2. Tears are also a natural aspect of the body's pain reaction.
  3. Humans are the only mammals known to cry in response to an emotional event, such as joy or despair.
