What's Mucus?
Mucus
Say: MYOO-kus
When you think of mucus, you might think of snot, which is that sticky stuff inside your nose. But that's only part of the story. You'll also find mucus in your mouth, lungs, stomach, and intestines. Wherever you find mucus, it protects and lubricates mucous membranes in your body.
