White blood cells only account for 1% of blood volume.
To my knowledge WBC's do not affect viscosity because that's not the purpose of WBCs and WBCs dont react to viscosity. It's the "other stuff" in plasma that makes it sticky i.e. viscosity. Viscosity reacts and increases only under certain circumstances. I.e. pregnancy, cancer, cuts bruises. This is why pregnancy and Cancer patients have a higher risk of PE, clots, thrombus.
I know that ,but why?? first reson it is the number of WBC and the seconed I dont know đ¤ˇââī¸đ¤ˇââī¸
viscosity formula is included of Force, area of each plate and rate of shear deformation. life time of WBC is another factor.
