Heart Valves Are Closed During Systole at Clayton Bond blog

Heart Valves Are Closed During Systole. The heart sounds are classically. Systole begins when the mitral valve (or tricuspid) closes and concludes with the aortic valve (or pulmonic) closure. This stage of the cardiac cycle represents ventricular. The classic heart sounds that we hear on physical exam are created by the closing of heart valves at various points during one round of a heartbeat. The two semilunar valves, the pulmonary and aortic valves, are closed, preventing backflow of blood into the right and left ventricles from the pulmonary trunk on the right and the aorta. During atrial systole, the atrioventricular valves open so that blood can enter the ventricles. During the early stages of ventricular diastole, both the atrioventricular and semilunar valves are closed. During this phase, there is no change in the amount of blood.
