Abstract
In this chapter velocity profiles, as recorded in mesenteric arterioles of the rabbit with the use of fluorescently labeled platelets as natural flow markers, are described. These velocity profiles are flattened parabolas with maximal and mean velocity ratios varying between 1.39 and 1.54 (median; 1.50). The wall shear rate values estimated from these velocity profiles, considering a two phase model, range from 472 to 4712 s−1 (median: 1700 s−1) for centerline red blood cell velocities varying between 1.3 and 14.4 mm.s−1. These wall shear rate values are at least 1.46 to 3.94 (median 2.12) times higher than those expected on the basis of a parabolic velocity profile, but with the same volume flow in the vessel.
