Q: -  You breathe in - Diaphragm and other muscles expand to allow room for your lungs to fill - The air flows into the narrow bronchioles in the lungs - From the bronchioles to the alveoli - The oxygen enters into the bloodstream - Is switched with the carbon dioxide in the bloodstream - The carbon dioxide enters through the alveoli - Through the narrow bronchioles - Into the lungs  What might be the last step of the process?
A: The carbon dioxide is exhaled out of the body.
