What's a Nasal Cavity?

Nasal Cavity

Say: NAY-zul KAH-vih-tee

The nasal cavity is the inside of your nose. It is lined with a mucous membrane that helps keep your nose moist by making mucus so you won't get nosebleeds from a dry nose. There are also little hairs that help filter the air you breathe in, blocking dirt and dust from getting into your lungs.
