Lung Demonstration Model
A firsthand view of how the lungs work.
This simple, yet effective apparatus consists of two sacs which represent the lungs, a rubber membrane which serves as the diaphragm and a clear plastic enclosure which models the chest cavity.
By making the diaphragm relax and contract the students can see how the lungs are emptied and filled with air.
