Systole: Period of ejection. AV valves closed Semilunar valves opened AV valves closed Semilunar valves closed Diastole: Period of isovolumic relaxation. Blood flowing back toward the relaxed ventricles causes the semilunar valves to close, which is the beginning of ventricular diastole.
Occurs as the continuing contraction of the ventricles increases the pressure in the ventricles and forces the semilunar valves open. At this point, blood is forces out of the ventricles. This interval ends when the ventricles begin to relax, and the semilunar valves close. The closing of the semilunar valves causes a small increase in blood pressure visible as the dicrotic notch on a plot of blood pressure against time. The amount of blood remaining in the ventricles at this time is called the End-Systolic Volume (ESV)
