ANATOMY

Detailed explanation-1: -Cardiac cycle events can be divided into diastole and systole. Diastole represents ventricular filling, and systole represents ventricular contraction/ejection.

Detailed explanation-2: -Ventricular contraction called systole. 2. Ventricular relaxation called diastole. Each part of the cardiac cycle consists of several phases characterized by either. a strong pressure change with constant volume or a volume change with a relatively.

Detailed explanation-3: -Ventricular systole contraction of the ventricles, forcing blood into the aorta and pulmonary artery. ventricular diastole period of relaxation and repolarization of the ventricular muscle.

Detailed explanation-4: -ventricles contract (ventricular systole); blood flows from the heart-to the lungs and to rest of body during ventricular ejection. Notes: Stages 1, 2a, and 2b together comprise the “Diastole” period; stages 3 and 4 together comprise the “Systole” period.

Detailed explanation-5: -The cardiac cycle is essentially split into two phases, systole (the contraction phase) and diastole (the relaxation phase). Each of these is then further divided into an atrial and ventricular component.
