Anatomical Heart

This is the vasculature of an actual heart (porcine heart, identical to human heart). The blood is replaced by a plastic substance which fills all of the veins, capillaries, etc, then the heart is put into a solution that dissolves all the tissue, leaving this incredible detail of a heart. My boss was given this to use as a model (he is a cardiologist).
