Blood going up to the heart does not flow backward because the veins that carry them have?

It does not flow backwards because when blood is pumped out, it is pumped through your arteries. Once your blood is done delivering oxygen and needs to go back to the heart, it goes to your veins through tiny "tubes" that connect your arteries and veins called capillaries. Also, the color of blood changes according to how much oxygen is in it. So when you get a cut, if the blood seems dark and almost maroon, it's probably from your veins. Artery blood is brighter because it has the oxygen.
The only thing I can think or that flows in and out is animals with exoskeletons. They don't have veins or arteries so blood just gets pushed out to their bodies and then pulled back in like the ocean or breathing.
