Check the listing for details. Health EDCO Occluded Artery Model Great Patient Visual Cholesterol Education. Condition: Used. Listed at 49.00 USD. Model allows viewers to peer inside an oversized artery and witness a grim series of events unfold. First, blood cells struggle to flow through the artery, which is clogged with thick, butter-colored plaque. As blood flow decreases, more blood cells pile up in the ever-narrowing gap. Finally, the cells stop moving altogether and—bam!—it’s a heart attack. There’s not a more sobering reminder of the importance of cholesterol control. • Model stands approximately 7” tall. Base and top are approximately 2-1/2” square. • Very good overall condition. Base shows a small dent in one corner (see photo), and light sticker residue. Clear plastic tube shows faint clouding on exterior in spots. Not noticeable, but worth mentioning.
