You are a little molecule of oxygen, floating in the air. Suddenly you feel a whoosh, and you are in a dark tube with little hairs tickling you. Is this that thing called the nose? Trace your journey from there to the alveoli of the lung; you will recognize it when you get there. It looks like a bunch of grapes. Name the structures along the way.
