ABSTRACT
By using a simplified model for cardiovascular system which consists of the cardiac resistance <i>R</i><sub>h</sub>, the artery <i>C</i><sub>a</sub>, the vein <i>C</i><sub>b</sub> and the peripheral vessel <i>R</i><sub>s</sub>, the ratio of the arteriovenous pressure difference Δ<i>p</i> to the maximum arteriovenous pressure difference Δ<i>p</i><sub>M</sub> was defined as the circulatory ratio θ ≡Δ<i>p</i> ⁄ Δ<i>p</i><sub>M</sub>. It was shown that the circulatory ratio θ was θ=1 ⁄ 2 regardless of the exercise. It was revealed that this regulation is done by keeping <i>R</i><sub>h</sub> ⁄ <i>R</i><sub>s</sub> constant and the ratio is equal to the arterial compliance fraction <i>k</i><sub>a</sub>.
