What's a Mucous Membrane?

Mucous Membrane

Say: MYOO-kus MEM-brain

Just as skin lines and protects the outside of the body, mucous membranes line and protect the inside of your body. You can find mucous membranes inside your nose, mouth, lungs, and many other parts of the body. Mucous membranes make mucus, which keeps them moist.
