Your Mouth and Nose
Your mouth and nose are very important, because they let air into your body. Did you know that your nose and mouth are connected? Your nose connects to the back of your mouth through two tubes. The air you breathe in goes from your mouth and nose down to your trachea and into your lungs.
 Your nose is really neat, because it is able to block some of the dirt and germs in the air. Your nose has hair in it that can block some of the stuff, but the most amazing part is the mucus that your nose makes. The dirt and germs in the air get stuck in the mucus in your nose, and they can't enter your lungs. When you blow your nose, you're getting rid of all the bad germs and dirt that your nose stopped from getting into your body!
