Figure 1 shows a color Doppler ultrasound picture of
blood flowing through a normal artery (red) and vein (blue). Figure 2 shows an
ultrasound picture of an artery narrowed by the buildup of calcium and fat
(cholesterol) in the inner lining of the artery, called plaque, which leads to
"hardening of the arteries" (atherosclerosis).
