HYDRODYNAMIC PROPERTIES OF ERTHROCYTES

Abstract

During the settling of an erythrocyte in a motionless fluid, it is oriented with the flat surfaces perpendicular to the axis of falling, which corresponds to the laws of hydrodynamics. The settling of an erythrocyte 'with the edge downward' in a narrow capillary and in the vicinity of the wall of a wide vessel is an exceptional case and is explained by the law of Poiseuille concerning the drop in pressure of a fluid at the wall of a vessel. As a result of the greater frontal resistance of an erythrocyte as compared to a globule, the formula of Stokes is not applicable for the rate of settling of an erythrocyte. On the basis of experimental data, a formula has been derived which takes into consideration the hydrodynamic peculiarities of the erythrocyte.
