Determinants of Inline graphic

Plot of O2 consumption (Inline graphic) against muscle venous Inline graphic showing the two conservation of mass equations describing convective flow of O2 into the muscle microcirculation (Fick principle), and subsequent diffusive flow of O2 from the microcirculation to the mitochondria (Fick law of diffusion). Conservation of mass occurs only at their point of intersection, indicating the value of Inline graphic when the independent variables Inline graphic, Inline graphic and Inline graphic are those at Inline graphic (modified from Wagner, 1996).
