Why doesn't blood ever flow the "wrong" way? *10 POINTS*?

Answers

their are valves in your vessels that stop it flowing the wrong way :)

#1

because you heart uses different tubes. like how we dont get water in and water out of the house mixed up

#2

through the veins and arteries? There are valves that control the direction of blood flow, it can only go one way

#3

Because blood flows in one way and out the other :) We watched a video on it and learned a song about it. Jeesh it was horrible.
