Flow models in a single vessel and vessel bifurcation. (A) Scheme of a single uniform cylindrical coronary vessel and its pressure boundary conditions: Pin, the inlet pressure; Pout, the outlet pressure; PT, the surrounding tissue pressure. (B) Lumped three-element Windkessel model of a single vessel segment consisting of two nonlinear resistors connected in series and a parallel nonlinear capacitor. (C) Lumped model of a single bifurcation of a parent vessel into two daughters.
