Ventricular Systole

Ventricular systole is the phase of the cardiac cycle during which the ventricles contract, pumping blood out of the heart and into the circulatory system.

Semilunar Valves

Heart valves located between the ventricles and the major arteries leaving the heart, which prevent the backflow of blood.

AV Valves

Atrioventricular (AV) valves are valves located between the atria and ventricles of the heart that prevent backflow of blood from the ventricles into the atria during contraction.

Afterload

The pressure against which the heart must work to eject blood during systole.
