The Original Heart of America is twice the size of a human adult heart to show detail and facilitate study. Three hinged portals allow full access to heart chambers and valves. Attached portions of trachea and esophagus demonstrate their relationship to major vessels. Unbreakable vinyl model fully rotates on wooden pedestal, or lifts off for pass-around viewing. Boasting no less than 63 cardiac structures, all of which are number-coded and identified in a corresponding key, this Giant Heart of America Model is renowned for its anatomical detail.
Overall dimensions on base: 7x7x15 inches (18x18x38 cm).
