WebHow is viscosity and blood pressure related? The greater the viscosity, the less easily molecules slide past eachother, and the more difficult it is to get the fluid moving and keep it moving. Because of the greater resistance, there is more pressure needed. What is hematocrit? The percentage of red blood cells in the total blood volume WebBoth hematocrit and plasma viscosity influence blood viscosity. The shear thinning property of blood is mainly attributed to red blood cell (RBC) rheological properties. RBC aggregation occurs at low shear rates, and increases blood viscosity and depends on both cellular (RBC aggregability) and plasma factors.
