Reply to comment by bonerfiedmurican in when a limb gets amputated, how do they stop the flow of blood? by EnchantedCatto

Could they... drain them a bit? Blood is made in the bones, and if you got a few fewer bones, technically you could have slightly less to pass around lol

blood isn't made at a constant rate but as needed, otherwise donating blood would permanently lower your blood pressure

it is not so much the amount of blood that is the problem but that the heart is used to pump against a given flow resistance and that resistance changes with the number of reduced "consumers". It is a little like with the electrical grid, when large consumers suddenly go offline/online, the power plants have to adjust their generation to not cause a systemic failure.
