WebSystole and diastole are two phases of the cardiac cycle that occur as the heartbeats, which pump blood through the system of blood vessels carrying blood to each part of the body. Systole occurs when the heart contracts, pumping blood out, while diastole takes place when the heart relaxes after contraction.
