Detailed explanation-1: -So, the correct answer is ‘Atrial systole, ventricular systole, ventricular diastole’.
Detailed explanation-2: -The cardiac cycle involves four major stages of activity: 1) “Isovolumic relaxation", 2) Inflow, 3) “Isovolumic contraction", 4) “Ejection".
Detailed explanation-3: -The ventricular function can be divided into four phases: isovolumic relaxation, ventricular filling, isovolumic contraction, and rapid ventricular ejection.
Detailed explanation-4: -Atrial diastole. Atrial systole. Isovolumic contraction. Ventricular ejection. Isovolumic relaxation. Ventricular filling.
Detailed explanation-5: -Atrial and Ventricular diastole (chambers are relaxed and filling with blood) Atrial systole (atria contract and remaining blood is pushed into ventricles) Ventricular systole (ventricles contract and push blood out through aorta and pulmonary artery)
