It sure does! Blood is carried back to the spleen, kidney, and liver where the blood is "cleaned" of the waste it was carrying before being recirculated. It also carries immune cells to/from your lymph nodes, oxygen, water, all sorts of stuff. Blood is more than just WBC/RBC!

Not joking, has anyone studied the potential anti-cancer benefits of substances that stimulate blood flow like caffeine and niacin?

I'm not sure, but that could be interesting.
