A "simple" cell method for concentrated suspnsions has been used to construct a model for the rheological behavior of blood. The model includes the physical properties of the suspending medium, red cell membrane and red cell fluid content. Predictions of the gross viscosity of red cell suspensions are found to agree very well with experiment in the cases of hardened red cells (or normal red cells at very low shear rate) and of normal red cells in the asymptotic limit of high shear rates. The behavior at intermediate shear rates requires a knowledge of the viscoplastic properties of the membrane and a number of membrane models are investigated. Of particular interest is plastic membrane which employs a membrane yield stress obtained from other experiments and whose results are qualitatively in agreement with the viscometric data at these intermediate shear rates.
