Four-stage cross-section of an artery demonstrating progressive atherosclerosis in which the narrowing
of the artery is due to a build up of fatty tissue (cholesterol) and plaque shown in. Shown in four
stages: 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.
