Dismemberment does not cause bleeding

[BaneOfGiygas]

I recall hearing from somewhere (I can't remember the source, so don't take this for 100% true) that the loss of a limb doesn't actually cause anywhere near as much bleeding as one might expect, because the veins in one's body actually go "oh shit wait there isn't a thing there that needs blood anymore" and so they stop bleeding and actually contract into the stump.

However, the loss of SOME blood would only make sense.
