It does, very slowly. That’s essentially what a bruise healing is: the blood breaks down, and the breakdown products are scavenged, partially recycled, and removed by the body.
But the bloodstream is under pressure. Ordinarily we measure blood pressure in millimeters of mercury for historical reasons, but if we measure it in the more familiar kilopascal, we find that normal blood pressure is around 11-16 kPa, that is, about 11-16% of atmospheric pressure (normal air pressure is ~100 kPa). That’s a substantial amount of pressure – it’s about the same amount of pressure you can exert by blowing air out of your mouth as hard as you can – and to get fluid back into such a pressurized environment, you would need a pump. The body does not have one to use. So even if it had a way of collecting the blood quickly, which it also doesn’t, it would have no way to get it back into circulation.
