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.
R-AV valve; the tricuspid valve contains- 3 cusps. L-AV valve; the bicuspid, or mitral valve- 2 cusps. -When AV valve is open, pointed end of cusps points into ventricle, and blood flows through into ventricles. -When ventricles contract the increase in pressure pushes the cusps upward until their edges meet. -At the same time the papillary muscles contract tightening the chordae tendineae. Semilunar valves:
