all of them

viscosity should be constant throughout the body..?

I would think so. The viscosity of blood depends on the concentration of plasma proteins,temperature, and the proportion of blood volume that is occupied by red blood cells. I dont think these qualities change as blood passes through out the circulatory system. But then again i have been proven wrong.

no, youre right ez. the only argument one could make is that blood is more viscous in the capillaries, perhaps, because the fluid has been pumped out on the arterial end (leaving proteins and ions making it more viscous) and is reabsorbed in the venous end of the capillaries. but otherwise viscosity is not a function of vessel radius. the speed, however, is.

1. Blood is a non newtonian fluid. http://en.wikipedia.org/wiki/Endorphin
2. Viscosity is dependent upon temperature. Is your finger the same temp as your core?
3. The viscosity is Dependant upon the cencentration inside the plasma
4. Are the pressure, shear, and normal forces the same throughout your body?

come on now.

As temperature decreases, viscosity increases. Viscosity increases approximate 2% for each °C decrease in temperature. How much does the blood differ at certain parts of the body?

3. The viscosity is Dependant upon the cencentration inside the plasmaAlthough the concentrations and types of proteins
in the plasma can affect its viscosity, this has little if any effect on
the overall viscosity of whole blood.

Is the viscosity of a substance dependent on the amount of external stress or force acting on it? I think not!

If the viscosity of blood does differ at certain parts in the circulatory system most likely these differences are very small.
