  • Operation of AV valve
    • Blood returning to the heart fills atria
      • pressure against atrioventricular valves
        • valves forced open
          • ventricle fills while AV valves hang limply to the side
            • Atria contract forcing additional blood into the ventricles
              • Ventricles contract forcing blood against the AV cusps
                • AV valves close
                  • Chordae tendineae tighten, prevents valve flaps from everting into atria
