Surface Chemical Aspects of Flow Characteristics of Blood
Blood is considered as a colloidal system in a broader sense which contains red and white cells as suspending particles and plasma as suspension medium. Red cells which constitute the main part of suspending particles are of the size of several micra - some 8µ in diameter and 2µ in thickness. This size surpasses the critical size for Brownian motion so that red cells fall with certain velocities in plasma containing anticoagulant. Whole blood is therefore not a stable colloidal system but, when in flowing state, in vitro or in vivo, it may be said to have hydrodynamic stability as a colloidal suspension.
