What structure of the heart prevents blood from flowing in the wrong direction?
Valve
The structure of the heart that prevents the backflow of blood is the heart valves. There are four valves in the heart that regulate the flow of blood. The atrioventricular (AV) valves, including the tricuspid valve and the mitral valve, prevent blood from flowing back into the atria when the ventricles contract. The semilunar valves, including the pulmonary valve and the aortic valve, prevent blood from flowing back into the ventricles when they relax. When the heart pumps, the valves open and close in a specific order to allow blood to flow in only one direction. The heart valves are essential in regulating blood flow and preventing the backflow of blood, which can cause heart problems.
