We presented a Power Band Graph(PBG) model to simulate blood fluid dynamics of the cardiovascular circulation system. The PBG modeling method described the blood fluid dynamic law in the circulation system by the state equation. Besides, the PBG modeling method was used to realize modeling on the human circulation system and conduct a simulation study on a simplified cardiovascular system model. The results demonstrated that the PBG method was quite effective and practicable. The study provided a simple and unitary simulation modeling method for cardiovascular system simulation.
