Figure 5. Fluid stresses on the surface of cell model with typical cell dimension and with smooth surface.
A–C) The normalized fluid stresses on the surface of a truncated sphere used to model an inactivated adherent leukocyte are shown. D–F) The normalized fluid stresses on the surface of a composite geometry that models an activated leukocyte with a large upstream pseudopod are shown. Both geometries have the same maximum height at 6µm and the largest stress value is lower in the case with the pseudopod. The stresses are displayed as a multiple of the applied wall shear stress, e.g. 5 is equivalent to 5×2.2dyn/cm2 = 11dyn/cm2.
