Lung Apparatus - LUNG01-B

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. Includes activity guide.
