Three hinged access portals swing open with the flip of your finger to reveal the faithful detailing of the interior of the heart chambers.
  Even more lifelike mitral and tricuspid valves with flexible chordae tendineae enhance understanding of valve action in controlling the directional flow of blood.
  Portions of the trachea and esophagus are included to demonstrate their relationship to the major vessels.
  No less than 63 cardiac structures, permanently number coded by hand, are identified in the key. (Our previous model had only 45.)
  Each Heart of America™ is 100% handcrafted in the United States from a custom-formulated vinyl plastic compound which is virtually unbreakable. Metal hinges for the access portals are bonded into the model. No screws to become stripped or work loose with usage!
  The model is meticulously hand painted in 10 vibrant colors guaranteed to retain their brilliance, integrity, and lifelike appearance.
  Because of its reputation for authentic detail, as well as durability, each model is proudly autographed and dated by the artisan who crafted it.
  The Heart of America™ is mounted on a genuine hardwood pedestal which permits easy rotation on the stand or quick removal to pass around. Size, 7 × 7 × 15" (18 × 18 × 38 cm).
