    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.
