This impressive kit provides an unforgettable hands-on demonstration of the effects of smoking. The Simulated Smoker's Lungs and the healthy Inflatable Pig Lungs can be inflated simultaneously to show how lungs are affected by smoking. Turning the valves at the top of the rack allows the lungs to be inflated individually. Smoker's lungs feature palpable internal and external tumors to reinforce to viewers that smoking causes lung cancer. Kit includes an interconnected airway system with dual trays, air pump, healthy lungs, smoker's lungs, and a section of dried lung with a storage container.
