When someone injures their wrist or ankle, for instance, we’re told that we must promote circulation to that area so it can heal faster. But how exactly does the blood passing through an affected area cause it to heal? It’s just passing through in the veins. Does the blood flow stimulate the tissue, or something?
In: Biology
Blood contains FIBRINOGEN that (in easy terms) seals up the cut portion. So more circulation means more blood passing through that cut portion, and that leads to more FIBRINOGEN in that portion and hence heals the injury.
There are other factors involved as well.. but I think it’s the primary.
