Experimental results for the stability of human blood, red cell suspensions and blood plasma to small disturbances in circular Couette flow are presented. The viscoelastic nature of whole blood and blood cell suspensions is confirmed. Blood plasma is found to be Newtonian. Elasticity is shown to have a sizably stabilizing effect on normal Hematocrit blood behavior. Two mechanisms by which elasticity may arise in blood are identified; namely red cell deformability and red cell aggregation.
