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 is now negative pressure in the ventricle (since it is now empty), and this pressure helps to draw in the blood from the atrium when it enters into systole. So during atrial systole (depending on which side we are talking about), the bicuspid/tricuspid valves are open, and the pulmonary/aortic semilunar valves are closed. Then during the diastole part, the bicuspid/tricuspid valves are closed (which makes sense, since we don't want blood from the ventricle getting back into the atrium).
