One heart beat occurs in 3 main stages. Firstly, Diastole occurs. This is where the atrial walls relax, and blood flows into the atria. The atrioventricular valves are open, and semi-lunar valves stay closed.
Next, Atrial Systole happens, where the atrial walls contract, forcing the atrioventricular valves open even more, and blood is forced into the ventricles. Semi-lunar valves stay closed.
Finally, Ventricluar Systole occurs. The ventricles contract, and semi-lunar valves open, whilst atrioventricular valves close, allowing blood to be forced into the Aorta and Pulmonary Artery :)
