Giant Heart With Pericardium And Diaphragm

Its large size making it ideal for group study, this heart separates into two parts, which makes it easy to trace blood flow through the chambers, valves and vessels. Featured - the coronary arteries, circumflex artery, coronary veins and coronary sinus, segments of the esophagus and trachea, lower portion of the pericardium, diaphragm section, flexible tricuspid valve, pulmonary valve, mitral valve and aortic valve.

Overall dimensions: 7x5x10 inches (17x13x25cm).
