Previous studies in our laboratory have shown that as the individual erythrocytes lose their deformabi1ity, the suspension viscosity increases and the shear thinning property disappears (1, 2). Significant differences in erythrocyte deformability have also been demonstrated among several animal species (3, 4), The results of these studies, as well as those by others (5, 6, 7, 8), indicate that the elastic properties of the individual erythrocytes play an important role in determining the suspension viscosity of blood as well as its shear dependence (9).
