Description

Hands on lung apparatus that demonstrates how the lungs are emptied and filled with air by relaxation and contraction of the diaphragm muscle.

  • Two balloons attached to a Y tube simulate the lungs.
  • The chest cavity is represented by a half-gallon plastic bell jar with an open top.
  • The stout rubber sheet acts as a diaphragm.
  • As the diaphragm is pulled downward the atmospheric pressure is lowered inside the chamber causing the lungs to expand taking in air.
  • When the diaphragm is released the lungs deflate.
  • Includes lesson plan.
