We just learned about the Nasolacrimal Duct.
Another part of the eye is the Eyelid, also called the palpebra, or palpabrea for both eyelids.
The upper eyelid is called the palpebra superior, and the lower is the inferior.
The job of the eyelids is to help protect the eye from wind, dirt or liquids, to help spread tears around the eye, and to close so that we can sleep at night.
Some people put makeup on their eyelids to color them, and some people even have plastic surgery on their eyelids to make them look higher or lower.
