AbstractFeatures of blood flow are explained in terms of structural rheological model. Flow curves at low shear rates are described by the generalized flow equation (plastic or pseudoplastic flow):  . At high shear rates the aggregates of red blood cells are completely destroyed, the Newtonian viscosity η N is practically equal to the Casson viscosity coefficient η c. The dependence of the magnitude of the Casson coefficient η c on the hematocrit (volume concentration Φ) is described by the equation  . Keywords: blood flow, hematocrit, structural rheological model
