Abstract

We developed a new method for visualizing the flow behavior of erythrocytes in living microvessels by the fluorescent labeling technique. Intravital microscopic observation of the microcirculation in the rat mesentery using this technique enabled quantitative analyses of a few hydrodynamic aspects of the two-phase blood flow; e.g. diameter-flow relationships in a consecutively branched vascular network and the distribution of erythrocytes in an arteriolar bifurcation.
