The External-Internal Heart is a twice life-size model so accurate it’s been endorsed by the American Heart Association. -- Three easy-access flaps flip open for internal study of the heart. The chambers and valves are accurately reproduced to scale. The flexible chordae tendinae and cusps permit easy-to-see demonstrations of valve action. The model includes attached sections of the trachea and esophagus. -- Mounted on a hardwood stand, this model comes with an answer key that lists the 45 structures permanently hand-coded on the model. -- Also twice life-size, the Heart with Bypass model (63708-00)has detachable bypass vessels to demonstrate single, double, triple, LIMA, and bilateral IMA coronary bypasses. Detaching all the vessels lets you show a normal healthy heart. |
