Abstract: In this study we investigate the blood flow in capillaries through rheological properties as small density limit of fluid. Here we know that blood viscosity is an important for flow of particle RBC, WBC and Platelets. The characteristics of blood flow exhibits shear thinning behavior of flow. It decreases exponentially with increasing shear rates. All these particles WBC, RBC and Platelets increases the viscosity of blood. The shear thinning property of blood is mainly attributed to red blood cell (RBC) rheological properties. RBC aggregation occurs at low shear rates with increase of these particles. Blood flow in human being artery and vein is highly dependent on the ability of RBC to deform, but deformability also affect on blood flow in the high and low concentration. When it is low concentration flow of blood is increases and rate of deformability is increased. The person with highest RBC deformability at steady–state has a higher risk of developing frequent painful. Moreover, regular physical exercise has been shown to decrease blood viscosity in sickle cell mice, which could be beneficial for adequate blood flow and tissue perfusion. The behavior of shear become less dense of blood in the low shear limit is analyses by assuming the approximate of the red blood cells (RBC). This is said to be the rouleaux form of blood. Here the fundamental equation blood flow in higher shear rate is obtained for the numerous flow positions by assuming the unique property of deformation of blood cells. In this study, the changes of the surface are conserving control. The tank treading flow of the blood cells on the rheological properties has been also investiged.
