Simulated Smoker's Lung Comparison Kit with Dual Rack
Best Seller!
With this set of simulated smoker’s lungs and healthy pig lungs mounted side-by-side for comparison, the damage done by smoking is painfully clear, becoming even more evident when the lungs are inflated. Smoker’s lungs feature palpable tumors, graphically reinforcing the idea that smoking causes cancer. Kit also includes a section of dried lung for closer inspection.
