No, it flows from the Right Atrium to the Right Ventricle then to the Left Atrium to the Left Ventricle. Hope this helps!

Why are valves separating the atrium and ventricles of the heart?
To regulate the flow of blood and to control it's speed.
What part of the heart acts like doors that control blood flow?
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.
What two atrioventricular valves control the flow of the blood?
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.
What are the function of the valves?
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.
What happens to A-V valves during ventricular contraction?
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.
Which cardiac structure control blood flow to the heart?
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
What is the function of the AV valves?
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.
What is the function of arterial outlet valves?
To prevent backflow of blood into the Ventricles.
What occurs during left ventricular relaxation?
open
What does the atrioventricular valve do?
The atrioventricular valves are two heart valves that allow for the transportation of blood from the atria to the ventricles of the heart. Its function is to prevent the return of blood to the atrium.
Do arteries have valves to allow blood to flow away from the heart?
No, they're aren't any valves in the arteries.
How do the valves between the atria and ventricles control the direction of blood flow?
The heart contains valves to prevent the backflow of blood. The right half of the heart has a "Triscupid Valve" and the left half of the heart has a "Biscupid Valve".
