No, it flows from the Right Atrium to the Right Ventricle then to the Left Atrium to the Left Ventricle. Hope this helps!
To regulate the flow of blood and to control it's speed.
The four valves in the heart are: * the two semi-lunar valves - one at the stem of the aorta, the other is found at the trunk of the pulmonary artery. * The tricuspid valve is on the right-hand side of the heart. * The bicuspid valve is on the left side of the heart.
When the ventricles are relaxed, the semilunar valves are closed, while the atrioventricular (AV) valves are open. This allows blood to flow from the atria into the ventricles. The closure of the semilunar valves prevents backflow of blood from the arteries into the ventricles during this phase.
The mitral or bicuspid valve and the tricuspid valve are the atrioventricular valves that control the flow of blood from the atria to the ventricles. The bicuspid is on the left side of the heart, and the tricuspid on the right.
The AV valves close in response to the contraction of the ventricles to prevent the backflow of blood from the ventricles into the atria, ensuring that blood flows in the correct direction through the heart and body.
As the ventricles of the heart contract the pressure in the ventricles rises beyond that of the atria. This pressure differential causes the AV valves to shut.
In cardiovascular health, heart valves are located between atria and ventricles in the heart. The valves will open significantly during the atrial depolarization, or contraction of the atria. During the subsequent re-polarization of the atria and depolarization of ventricles, the valves are pushed in the opposite direction and shut closed. This mechanism allows the flow of blood in one single direction only, from atria to ventricle.
The atrioventricular valves are responsible for preventing blood from flowing back into the atria at the moment the ventricles contract. These valves are situated at the point where the ventricles and atria meet. Atrioventricular valves are two in number; the mitral valve and tricuspid valve.
The semilunar valves control the flow of blood from the heart. The aortic semilunar valve controls the flow of blood from the left ventricle to the aorta, and the pulmonary semilunar valve controls the flow of blood from the right ventricle to the pulmonary artery.Pulmonary valve

open
The valves in the auricles (atria) and ventricles of the heart ensure unidirectional blood flow throughout the cardiac cycle. The atrioventricular valves (tricuspid and mitral) prevent backflow of blood from the ventricles to the atria during contraction, while the semilunar valves (pulmonary and aortic) prevent backflow from the arteries into the ventricles during diastole. This coordinated function is crucial for efficient circulation and maintaining proper blood pressure within the heart and vessels.
