The influence of the change in the temperature 
and the acidity of blood on its hemorheological properties has been 
analyzed. It is shown that, at temperatures lower than 45oC, the 
temperature dependence of the apparent viscosity of blood at a rate 
of shear ranging from 0.3 to 50 sec-1 is adequately defined 
by the Arrhenius model with a viscous-flow activation energy of 13-17 
kJ/mole. In the range of pH 6.3-7.6, the oversouring of blood mainly 
influences the critical shear stress, and the Caisson viscosity depends 
only weakly on the acid-base equilibrium.
