The inflatable swine lungs have been stained realistically and then specifically preserved by the BioFlex odorless, nontoxic process that retains the texture and elasticity of fresh lungs * The lungs dramatically and unforgettably demonstrate the effects of prolonged smoking * A palpable simulated internal tumor and a physical simulated external tumor encourage students to feel the texture of the lungs, and to remember that smoking is a known cause of lung cancer * The Simulated Smoker's Lungs can be used with the Inflatable Lungs Kit * The kit includes: * a Teacher's Guide * a Pamphlet * an Inflation rack and tray * Air pump * a Dried section of unstained lung * and a Pair of simulated smoker's lungs * Grade 6-Adult
