What structure in the veins prevents blood from the flowing toward the heart?

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.

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.

∙ 11y agoThere 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:

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