This Lung Function Model shows 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 plastic bell jar with an open top and stout rubber sheet which 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.
