What is the cardiac cycle?

The human heart's activity from the start of one heartbeat to the start of the next is known as the cardiac cycle. It consists of two phases: diastole, in which the heart muscle relaxes and re-fills with blood, and systole, in which the heart muscle contracts forcefully and pumps blood. The heart quickly relaxes and expands after emptying to receive a second inflow of blood returning from the lungs and other body systems, then contracts to send blood back to those systems.
