PPT-The Cardiac Cycle

Learning Outcomes During diastole blood returning to the atria flows into the ventricles Atrial systole transfers the remainder of the blood through the atrioventricular AV valves to the ventricles Ventricular systole closes the AV valves and pumps the blood out through the semi lunar SL valves to the aorta and pulmonary artery In diastole the higher pressure in the arteries closes the SL valves The opening and closing of the AV and SL valves are responsible for the heart sounds heard with a stethoscope .
