Fig. 7 — The two-compartment Krogh model. In this model the systemic circulation has a large compliant region (such as the splanchnic vasculature) in parallel with a low-compliance region (equivalent of the peripheral vasculature). A shift in the fractional flow to the low-compliance region by decreasing the arterial resistance (Ra-p) into this region decreases venous resistance (upward shift of the slope in b compared with a) but does not change MCFP. Rv-s is splanchnic venous resistance, Rv-p is peripheral venous resistance. (Used with permission from reference [5])
