How is blood kept moving backwards in your veins?
Your veins have a system of valves that work to keep the back flow of blood from returning the areas where blood has already passed. Once the left ventricle of the heart has finished contracting, gravity will tend to pull blood downward. When this happens, blood pushes back the valves, forcing them closed. The valves will reopen when the force of the blood being pumped exceeds the amount of force opposing the valves. As a side note, valves work to allow flow of a fluid in one direction only. Sphincters (such as your cardiac sphincter in your stomach) allow for fluid or in the stomach's case, a bolus, to enter and exit your stomach, allowing an individual to vomit. Rats and horses do not have cardiac sphincters, thus making it impossible for them to vomit.
