- Modeling Human cardiovascular system is always an important issue. One ofthe most effective methods is using lumped model to reach to a complete modelof human cardiovascular system. Such modeling with advanced considerations isused in this paper. Some of these considerations are as follow: Exactsimulating of ventricles as pressure suppliers, peristaltic motion ofdescending arteries as additional suppliers, and dividing each vessel into morethan one compartment to reach more accurate answers. Finally a circuit withmore than 150 RLC segments and different elements is made. Then theverification of our complex circuit is done and at the end, obstruction as animportant abnormality is investigated. For this aim different percents ofobstruction in vital arteries are considered and the results are brought asdifferent graphs at the end. According to physiological texts the citation ofour simulation and its results are obvious. To earn productive informationabout arteries characteristics a 36-vessels model was chosen from biologicalsources.
