The venous blood is thicker, since some plasma is taken up by the lymph system.

Just a guess, not sure, but I am actually studying hematology in my nursing class as we speak, and maybe where the venous RBC's have already dropped the oxygen to the tissue after being carried through the arteries, it decreases the size of the cell.

I am not sure where you got the idea about RBCs being of different sizes in the veins and arteries.
RBCs are on an average about 7.5 microns in diameter. What could possibly make them look bigger is that veins are smaller in diameter and hence the RBCs are almost packed into them while they move with much more freedom in the artery.
