Semilunar valves are open. Blood is leaving the heart. AV valves are closed. Semilunar valves are closed. Blood is entering the heart. AV valves are open. Blood is flowing through semilunar valves. Blood is flowing through AV valves Ventricles are contracting Ventricles are relaxed. Mr. G has mitral regurgitation. How has this caused a systolic murmur? First of all, let's sort out what is happening during systole and diastole. Must be match which goes to Systole and which one goes to Diastole

Semilunar valves are open. B. Pressure in the heart is high. C. Atria contract to force the remaining blood into the ventricles. D. Atrioventricular valves are open. E. Blood flows passively from veins through atria into ventricles.
