In this paper, we analyze chaotic behavior observed from human circulatory systems using the well-known Windkessel model. A theoretical result reveals a quantitative mechanism of the chaotic behavior. That is, the origin of chaotic behavior is in its time-delay and nonlinear elements that are effective for a physiologically plausible range of parameters value. Simulation results also show a physiologically plausible behavior from periodic to chaotic dynamics for the parameters value derived from the theoretical analysis. We further analyze a chaotic itinerant model to explain complex mode transitions in human circulatory systems and discuss a possible application of the itinerant model to the circulatory systems.
