Anatomically speaking, the model can be used to gain an understanding of both the surface anatomy of the heart, but also the structure of the individual heart chambers and the valves between them.
The model shows both atria, with right and left auricles respectively, and both ventricles. In addition, the large arteries and veins that run to and from the heart are seen:
Aorta
Ah. pulmonales (pulmonary arteries)
Vv. pulmonales (pulmonary veins)
Superior and inferior vena cava
In addition, the heart's own blood supply is seen, consisting of the right and left coronary arteries and their branches. On the back of the heart, the coronary sinus is seen, where the veins that drain the heart empty.
The valve system of the heart is also seen. Between the atria and ventricles are the two lobed valves of the heart (the tricuspid valve and the mitral valve) and between the right ventricle and truncus pulmonalis, and the left ventricle and the aorta, are the two sacral valves of the heart (the aortic valve and the pulmonary valve).
When the front surface is removed, you get a sense of the three layers of the heart wall - the endocardium, the myocardium and the epicardium. Furthermore, it can be seen how the wall thickness in the left ventricle is significantly greater than in the right ventricle.
The heart's impulse conduction system is not depicted.
