Two balloons attached to a Y-tube simulate the lungs.

When the diaphragm is released, the lungs deflate.

This simple model demonstrates the functioning of lungs for students.

The chest cavity is a bell jar with open top and stout rubber sheet that acts as the diaphragm.

This depicts how the lungs are emptied and filled with air by the relaxation and contraction of the diaphragm muscle.

As the diaphragm is pulled downward, the atmospheric pressure is lowered inside the chamber, causing the lungs to expand and take in air.
