Lung Apparatus
Demonstrates how the lungs are filled and emptied with air through
contraction and relaxation of the diaphragm muscle. The two balloons act
as the lungs and the rubber sheet acts as the diaphragm. Pulling the rubber
sheet downward created pressure within the chamber causes the balloons to
expand. Releasing the rubber sheet deflates the balloons.
