Blood is a viscoelastic fluid and its rheological properties, viscosity and elasticity, depend on the rate of flow or shear rate. The changes in viscosity and elasticity are a result of changes in the arrangement, orientation and stretching of the red blood cells. The viscoelastic profile of normal human blood can be divided into three regions: Region A Low Shear Rates, Region B Mid-Shear Rates and Region C High Shear Rates.
