Definitions:

AV Valve

Atrioventricular valves, which are located between the atria and ventricles of the heart, preventing backflow of blood from the ventricles into the atria.

Atrial Systole

The contraction of the atria chambers of the heart, which pushes blood into the ventricles.

Ventricular Systole

The phase of the cardiac cycle in which the ventricles contract, pumping blood out of the heart to the lungs and the rest of the body.

Isovolumetric Contraction

A phase in the cardiac cycle where the heart's ventricles contract with no change in volume because all valves are closed.
