| What do you call the sheet of muscles that moves up and down to draw oxygen into to the lungs and expel carbon dioxide out | Diaphragm |
| How thick are the walls of the alveoli | One cell thick |
| Name one disease that can be caused by smoking | Cancer |

| If carbon dioxide is present, what happens | Limewater turns milky |
| What do you call the process of taking air into the lungs | Inhalation |
| What do you call the process of pushing air out of the lungs | Exhalation |
| During inhalation does the diaphragm move up or down | Down |
