A mock circulation system is provided including a collapsible housing having a plurality of channels formed therein so as to represent the arteries, veins and organs of a human circulatory system. A pair of artificial ventricles are connected to the housing and pump fluid through the housing so as to develop circulation within the housing. By using a plurality of flow-restricting devices, and by modifying the pumping of the artificial ventricles, a variety of circulatory conditions (both healthy and pathogenic) can be simulated within the system. In accordance with the principles of the invention, cardiac massage may be demonstrated by manually squeezing the artificial ventricles. In accordance with another principle of the invention, Starling's Law Curves may be generated to show that cardiac output is determined by venous pressure.
