Cardiac Cycle Diastole Phase Early Diastole Ventricles relax. Semilunar valves close. Atrioventricular valves open. Ventricles fill with blood. Mid Diastole Atria and Ventricles are relaxed. Semilunar valves are closed.Atrioventricular valves are open. Ventricles continue to fill with blood.Late Diastole SA node contracts. Atria contract. Ventricles fill with more blood. Contraction reaches AV node.trioventricular valves open. Ventricles fill with blood. Mid Diastole Atria and Ventricles are relaxed. Semilunar valves are closed. Atrioventricular valves are open. Ventricles continue to fill with blood. Late Diastole SA node contracts.
There are also two semilunar valves; one between the right ventricle and the lungs (pulmonary semilunar valve) and one between the left ventricle and the aorta (aortic semilunar valve). The main purpose of the valves is to prevent backflow of blood in the heart. There are things called the chordae tendinae and papillary muscle that help control the opening and closing of the valves as blood flows through them. There are also valves in the veins.
