the valves
the aorta valve prevents the blood from coming back from the aorta to the left ventricle.
the pulmonary valve prevent the blood from flowing back from the pulmonary artery to the right ventricle.
the mitril valve prevents blood from flowing from the left ventricle back into the left atrium
the tricuspid valve prevents blood from flowing from the right ventricle back into the right atrium.

Your heart has four different chambers: the left and right ventricles, and the left and right atria (atrium = singular). When blood flows through your heart, each chamber pumps blood into different parts of the body (the lungs, the brain, etc.) - so naturally, it would be disastrous if the blood flowed backwards! There are certain things called valves, which are almost tubelike, that reside in each chamber of the heart - this prevents blood from flowing in the wrong direction, whether it is to the wrong part of the body or into another chamber.

Bicuspid and Tricuspid valves between ventricles and atria prevent the back flow of the blood inside the heart and aortic and pulmonary artery's semi-lunar valves prevent the blood to flow back onto the heart.

Valves prevent the backflow of blood.
Atrioventricular valves (tricuspid valve and mitral/bicuspid valve prevents blood from flowing back into the atria, from the ventricles)
Semilunar valves prevent blood from flowing back into the ventricles.
The mendian septum is the wall separating the left and right sides of the heart, prevent oxygenated and deoxygenated blood from mixing.
