"If we review Co2 transport from tissues to venous blood: there is formation of HCO3 ion , which exits from RBC and is followed by entry of Chloride ions (aka Chloride Shift). Presence of Bicabonate and entry of Chloride ions inc the osmotic pressure of venous RBC and water follows inside RBC.
Therefore Vol of Venous RBC > Vol of Arterial RBC
And hence HCt of Venous blood is higher"

I would also assume that Hct is increased due to fluid movement from capillaries to lymphatics, with the lymphatic fluid only being reintroduced to the venous system at the venous angles.
