This resilient vinyl heart divides into anterior and posterior sections to access its pumping chambers and valves. Fitted with detachable/re-attachable bypass vessels for demonstrating single, double, and triple coronary bypass grafts, as well as normal heart without bypasses.

Vibrant handpainted colors permanently bond with the vinyl model, and are guaranteed not chip, crack, fade, peel or transfer. Vessels are color-coded red or blue to indicate whether they carry oxygenated or deoxygenated blood. Significant cardiac features, 33 in all, are hand numbered on the model for identification in the accompanying key.

Nesting on a form-fitting display base, the heart lifts off for hands-on observation and study. Overall dimensions: 4x4x6 inches (11x11x15cm).
