ANATOMY

Detailed explanation-1: -Diastole represents ventricular filling, and systole represents ventricular contraction/ejection.

Detailed explanation-2: -The cardiac cycle is essentially split into two phases, systole (the contraction phase) and diastole (the relaxation phase).

Detailed explanation-3: -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-4: -What is Systole and Diastole? – Define Systole and Diastole. The contraction of the muscles of the heart is referred to as systole, while the relaxation of the heart muscles is referred to as diastole.

Detailed explanation-5: -The cardiac cycle is the rhythmic contraction and relaxation of the heart. Contraction is called cardiac systole and Relaxation is called cardiac diastole. Both contraction and relaxation are together known as the cardiac cycle.
