Explanation:
Detailed explanation-1: -The cardiac cycle is a series of pressure changes that take place within the heart. These pressure changes result in the movement of blood through different chambers of the heart and the body as a whole.
Detailed explanation-2: -The cardiac cycle describes all the activities of the heart through one complete heartbeat-that is, through one contraction and relaxation of both the atria and ventricles. A contraction event (of either the atria or ventricles) is referred to as systole, and a relaxation event is referred to as diastole.
