Oxygen-poor blood (shown in blue) flows from the body into the right atrium. Blood flows through the right atrium into the right ventricle. The right ventricle pumps the blood to the lungs ...

It illustrates blood flow dynamics through the heart's chambers, including the right atrium, right ventricle, and pulmonary arteries, as well as the return of oxygenated blood from the lungs to ...

The semilunar valves stop the back flow of blood into the heart ... It goes into the right atrium, through the tricuspid valve and into the right ventricle. The ventricle pumps the blood through ...
