Description

This simple model demonstrates the mechanisms of breathing for students.

• Shows how the lungs are emptied and filled with air by the relaxation and contraction of the diaphragm muscle
• One or two balloons attached to a Y-tube simulate the lungs
• The chest cavity is a half-gallon bell jar with open top and stout rubber sheet that acts as the diaphragm
• As the diaphragm is pulled downward, the atmospheric pressure is lowered inside the chamber, causing the lungs to expand and take in air
• When the diaphragm is released, the lungs deflate
