The Deluxe Lung Model Apparatus is a visual demonstration of how a lung is emptied and filled with air by the relaxation and contraction of the diaphragm muscle. Two balloons are attached to a glass "Y"-tube and simulate the lungs. The chest cavity is a plastic bell jar. The rubber sheet is used to represent the diaphragm. As the diaphragm is pulled downward, the atmospheric pressure is lowered inside the chamber, causing the lungs to expand. The approximate size is 8" x 8". Instructions included.
