This two-part model, enlarged 2¹/₂ - 3X, is ideal for group study because of its prominent size and enhanced visibility.
It shows both atria with auricles, the coronary sulcus, the coronary and pulmonary blood vessels, and segments of the esophagus, trachea, aorta, and vena cava.
Students can remove the anterior wall to study the internal structures, including the entrance points of the superior and inferior vena cavae and flexible tricuspid, mitral, and aortic valves.
The model is attached to a base, which represents a portion of the pericardium resting in its natural position on the diaphragm.
