Models Human Biology Models
Demonstrate how the diaphragm causes the lungs to inflate.

  • Balloons fill, representing the lungs
  • Sealed system similar to the human chest cavity
  • Includes activity guide
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 creates pressure within the chamber, and causes the balloons to expand. Releasing the rubber sheet deflates the balloons.
