[Association between the hemodynamic and rheological parameters in the micro blood vessels in vivo].
Considering the experimental data obtained earlier, regarding the shift velocity in the micro blood vessels in vivo, and general theses of liquid mechanics and rheology of the non-Newtonian liquids, a generalized ratio between the hemodynamic and rheological parameters in the micro blood vessels in vivo are overviewed. These are: pressure difference--DeltaP, volume of blood flow--Q, linear velocity of blood flow, viscosity of Newtonian liquid--k, effective viscosity of the blood in a vessel in vivo eta(effect), and index of rheological behavior--n, which was determined earlier in our laboratory. These parameters are observed in the live blood vessels of microcirculatory bed, in all regimes of the blood flow characteristic for the in-vivo vessels.
