The heart has four chambers - left atrium, left ventricle, right atrium & right ventricle.
The left chamber holds oxygenated blood while the right chamber holds deoxygenated blood. The two sides of the heart are separated by an interventricular septum between the ventricles, and an interatrial septum between the atria.
The Pulmonary circulatory system carries deoxygenated blood from the right side of the heart to the lungs for oxygenation and brings the oxygenated blood back into the left side of the heart.
The Systemic circulatory system carries oxygenated blood from the left side of the heart to the rest of the body where the oxygen is depleted, and then back into the right side of the heart.
Valves
Rt (AKA tricuspid) and Lt (AKA biscupid or mitral) AV valves prevent back flow from the ventricles back into the atria
The Aortic and Pulmonary semilunar valves prevents back flow from the Aorta or Pulmonary Trunk back into the ventricles.
There is nothing like that . There is such a thing like semi-lunar valves that prevent blood flowing in the other direction because of low pressure in the veins . The blood in the veins (de-oxygenated) will eventually flow to the heart . So its like this : Veins -> heart -> lungs (oxygenation takes place) -> heart -> artery -> veins :REPEAT:
oxygenated blood is prevented from mixing with deoxygenated blood by the septum....i should know O.o

What structure prevents blood from backing up?
In the heart/arteries, the Aortic valve prevents blood from flowing backwards. In the systemic veins, eustachean valves prevent the backwards flow of blood.

What prevents blood from flowing in veins?
veins contain valves that prevents blood flowing backwards between heartbeats.There are valves in the veins that stop the blood from flowing backwards.
