WebCoupling of the venous system of the heart is graphically represented in Figure 17 (c). In this analysis developed by Guyton and coworkers, the intersection of the ventricular function (Frank–Starling) curve and the venous return curve represents the steady-state operating values of cardiac output and venous pressure (Guyton et al., 1973).At this equilibrium … Web7 de mar. de 2011 · system when, by definition, venous return equals cardiac output and when systemic resistances and capacitances are constant. During transitions between steady states when blood volume is shifting among compartments, venous return and cardiac output will transiently be unequal, as elegantly described by Brengel-Fig. 1. … river plate anglers brazil
