- heart cycle
- ventricular diastole (late)- all chambers are relaxed; passive ventricular filling occurs
- atrial systole begins- atrial contraction forces a small amount of additional blood into ventricles
- atrial systole ends, atrial diastole begins- atrial contraction ends and ventricular contraction begins
- ventricular systole (first phase)- ventricular contraction pushes AV valves closed but does not generate enough pressure to open SL valves
- ventricular systole (second phase)- as ventricular pressure rises and exceeds pressure in the arterial trunks, the SL valves open and blood is ejected
- ventricular diastole (early)- as ventricles relax, ventricle pressure drops; blood flows back against SL valves and forces them closed. blood flows into the relaxed atria
