Demonstrating the benefits of a healthy cholesterol level and the deadly effects of high cholesterol, this model will leave an impression that lectures and books 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, while the blood in the occluded artery slows and even stops completely. 

Made of durable plastic.
