Cardiac Cycle - Systole & Diastole
Educational only: videos on MedicalVideos.com are for general information and are not medical advice. Always consult your own doctor about your health.
Near the end of diastole, the ventricles nearly fill with blood, and then the atria contract, adding even more volume to the ventricles. The volume of blood in the ventricles at the end of diastole is referred to as the end-diastolic volume. The other phase of the cardiac cycle is called systole.

This video explains the cardiac cycle, focusing on diastole and systole. It describes how near the end of diastole the ventricles nearly fill with blood and the atria then contract to add even more volume, defines the end-diastolic volume as the volume of blood in the ventricles at the end of diastole, and identifies systole as the other phase of the cycle.
