Document Summary

Cardiac cycle: atria (summary, in order: relaxed atria, blood ows into (and through) atria, atria contract (atrial systole, blood ows into ventricles, atrial relax (atrial diastole, decreased pressure in atria. As the ventricles contract (ventricular systole), the bicuspid valve and tricuspid valves close, and blood ows out of the ventricles into the arteries. When the ventricles relax (ventricular diastole), the bicuspid and tricuspid valves open, The maximum amount of blood in ventricles occurs at the end of ventricular relaxation. Esv: end-systolic volume or minimum amount of blood in ventricles. Two-thirds of the cycle is ventricular diastole, one-third of cycle is systole. Produced from the vibrations caused by valve closure. When the tricuspid and bicuspid valves close. When the pulmonary and aortic semilunar valves close. Highest volume at the end of ventricular diastole. The volume of blood ejected from the ventricle with each beat (stroke) of the heard. As you make your heart stronger, your heart has fewer beats per minute.
