Mechanism of Red Cell Aggregation
This chapter will discuss the mechanism of red cell aggregation as one of the predominant determinants of the flow characteristics of blood, particularly in low-flow states. If one investigates the roles of viscosity of whole blood or at least a good model of it — namely red cells suspended in human plasma anticoagulated with, for example, citrate — measurements are often made as a function of the shear rate. The shear rate itself is just a measure of how fast the blood is moving in the container, whether it be a blood vessel or the cup of a rotating viscometer. It is a measure of how fast the velocity is changing away from the wall of the container; thus it is the rate of change in velocity and it is measured in units of inverse seconds.
