Answer 1

heya buddy,
The cardiac cycle is the sequence of events that occurs when the heartbeats. As the heart beats, it circulates blood through pulmonary and systemic circuits of the body. There are two phases of the cardiac cycle. In the diastole phase, the heart ventricles are relaxed and the heart fills with blood.
