One of the most important problems of model hemodynamics is the descriptions of the rheological properties of the flowing blood. In this work, two basic classes of a hemorheology models have been analysed. The first one considers human blood as a non-Newtonian and time-independent fluid. However, the dynamical formation of its time-dependent collective structure leads to a viscoelastic and tixotropic blood response. In consequence, this study presents a second class of hemorheology model, considering blood as a fluid thinning and thickening with time.
