Detailed explanation-1: -The period of relaxation is called diastole in which the ventricle fills with blood and the period of ventricle contraction is called systole. Fig. 4.4 shows the cardiac cycle events for the left pump of the heart for two complete cycles.
Detailed explanation-2: -systole-this is when your heart contracts, pushing blood out of the chambers. diastole-this is the period between contractions when the muscle of your heart (myocardium) relaxes and the chambers fill with blood.
Detailed explanation-3: -Cardiac cycle events can be divided into diastole and systole. Diastole represents ventricular filling, and systole represents ventricular contraction/ejection.
Detailed explanation-4: -The cardiac cycle is essentially split into two phases, systole (the contraction phase) and diastole (the relaxation phase).
