In this paper, we analyze chaotic behavior observed from human circulatory systems using Cavalcanti's circulatory model. A 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 physiologically
