Detailed explanation-1: -Ventricular systole: lasts about 0.3 seconds-both ventricles contract, blood is forced to the lungs via the pulmonary trunk, and the rest of the body via the aorta. Atrial diastole: lasting about 0.7 seconds-relaxation of the atria, during which the atria fill with blood from the large veins (the vena cavae).

Detailed explanation-2: -A healthy human heart beats 72 times per minute which states that there are 72 cardiac cycles per minute. The cardiac cycle involves a complete contraction and relaxation of both the atria and ventricles and the cycle last approximately 0.8 seconds.

Detailed explanation-3: -Ventricle systole: Both the ventricles contract to move blood out to their target areas and stay for about 0.3 seconds. Ventricle Diastole: Both the ventricles relax to receive blood from both the atria. It lasts for about 0.5 seconds.
