Demonstrating the benefits of a healthy cholesterol level and the deadly effects of high cholesterol, this model will leave an impression that lectures and textbooks cannot. The model's two tubes represent a normal artery and an artery constricted by plaque. When the model is turned over, the blood in the healthy artery flows swiftly to the top, but the blood in the occluded artery slows and even stops completely. Made of durable plastic.
