Explanation:

Without oxygen, the body's cells would die. ... The lungs and respiratory system allow oxygen in the air to be taken into the body, while also enabling the body to get rid of carbon dioxide in the air breathed out.

Note that air bubbles in via the left boiling tube, as indicated on the diagram. Without removing your mouth from the apparatus, breathe out gently. Note that air bubbles out via the other boiling tube.
