ANATOMY

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: -Systole is the contraction phase of the cardiac cycle, and diastole is the relaxation phase. At a normal heart rate, one cardiac cycle lasts for 0.8 second.

Detailed explanation-3: -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-4: -Systole is best described as the period that starts when the heart is maximally filled with blood and then subsequently ejected from the ventricle to the aorta whereupon the aortic valve closes. The volume of blood ejected from the heart is the stroke volume (SV).

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