Detailed explanation-1: -Cardiac cycle events can be divided into diastole and systole. Diastole represents ventricular filling, and systole represents ventricular contraction/ejection. Systole and diastole occur in both the right and left heart, though with very different pressures (see hemodynamics below).

Detailed explanation-2: -In heart. This process is called the cardiac cycle. The period of relaxation is called diastole. The period of contraction is called systole.

Detailed explanation-3: -systole, period of contraction of the ventricles of the heart that occurs between the first and second heart sounds of the cardiac cycle (the sequence of events in a single heart beat). Systole causes the ejection of blood into the aorta and pulmonary trunk.

Detailed explanation-4: -The heartbeat is caused by the heart muscles relaxing and contracting. During this cycle, the period of relaxation is called diastole and the period of contraction is called systole.

Detailed explanation-5: -Meaning: Gorgeous. Glittering and beautiful. A beautiful pattern in a textile.
