Indeed, any changes in one or several of these parameters may affect blood viscosity differently. Blood flow in the microcirculation is highly dependent on the ability of RBC to deform, but RBC deformability also affects blood flow in the macrocirculation since a loss of deformability causes a rise in blood viscosity. RBC aggregation occurs at low shear rates, and increases blood viscosity and depends on both cellular (RBC aggregability) and plasma factors. The shear thinning property of blood is mainly attributed to red blood cell (RBC) rheological properties. Both hematocrit and plasma viscosity influence blood viscosity. Blood viscosity is an important determinant of local flow characteristics, which exhibits shear thinning behavior: it decreases exponentially with increasing shear rates.
