Artery Model 4 piece set

This model includes a 4-stage cross-section of an artery demonstrating atherosclerosis in which the narrowing of the artery is due to a build up of fatty tissue (cholesterol) and plaque. The 4 stages illustrate normal artery, fatty streak, fibrous plaque, and blockage. The stages cause a decrease in blood flow, which can lead to a blood clot or thrombus. All stages rotate on hinge pin. Size: (4) 1-3/8”dia. x 7/8”x 3-1/2”.
