in the heart blood flows from the right atrium to the right ventricle where it is pumped to the...?
What? I'm pretty sure this is easy, i'm just stumped-_-

is it lungs?
ach side of your heart uses an inlet valve to help move blood between the atrium and ventricle. The tricuspid valve does this between the right atrium and ventricle. The mitral valve does this between the left atrium and ventricle. The "lub" is the sound of the tricuspid and mitral valves closing.
Each of your heart's ventricles has an outlet valve. The right ventricle uses the pulmonary valve to help move blood into the pulmonary arteries. The left ventricle uses the aortic valve to do the same for the aorta. The "DUB" is the sound of the aortic and pulmonary valves closing.
Each heartbeat has two basic parts: diastole (di-AS-toe-lee), or relaxation, and atrial and ventricular systole (SIS-toe-lee), or contraction.
During diastole, the atria and ventricles of your heart relax and begin to fill with blood. At the end of diastole, your heart's atria contract (atrial systole) and pump blood into the ventricles. The atria then begin to relax. Next, your heart's ventricles contract (ventricular systole) and pump blood out of your heart.
