Hmm....this is a off the cuff guess, not being a medical expert. But with
the Spleen able to trim off excess dead red blood cells, does it also
regulate the total red blood cell count in the blood stream? If so, this
would add a regulating element to the bloodstream that would be lacking in
any tissue system that was given similar regrowth potential.
