Explanation:
Detailed explanation-1: -Cardiac cycle events can be divided into diastole and systole. Diastole represents ventricular filling, and systole represents ventricular contraction/ejection.
Detailed explanation-2: -Systole is the contraction phase of the heartbeat. During this phase, the right and left ventricles contract to pump blood to the lungs and body. Blood pressure measures pressure during both ventricular contraction (systolic pressure) and during relaxation (diastolic pressure).
