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. Size 9” x 4.5”.
