That’s not really how the circulatory system works. Mainly blood just flows away from the heart, then back to the heart. Blood does not travel from one limb to the next limb. It’ll go from the heart, to your fingers, back to your heart, and then maybe this Time it goes down the other branch to your toes.
So if your leg is amputated below the knee, the only body parts that blood would go to are already cut off.
