A bond graph model of entire cardiovascular system is developed in this paper. Although relying on the concepts of previously developed lumped-parameter models, this new model benefits from some advantages of general system theory which allows the modeler to include as many details as necessary. Specifically, inclusion of pace making mechanism has become much easier. The pace making mechanism is not, however, included in this stage of model development. Modular sources of effort are, instead, predicted in the model to generate synthetic signals close to what occurs in reality. The model is simulated and results of simulation are compared with widely available data of normal cardiovascular system's pressure-flow performance. It has been shown that they are of a good agreement and the model could successfully simulate performance of the human cardiovascular system
