A dramatic tabletop display, this set of five artery models graphically shows the smothering effect of waxy plaque buildup inside a coronary artery. As the opening in the artery gets smaller, a heart attack becomes increasingly imminent because of impeded blood flow. The display also emphasizes risk factors for heart disease and working with your healthcare professional to manage risk factors within your control. Comes with protective fleece cover. 9" x 12".
