Diastole is the relaxation phase of the heart muscle during which blood flows from the atria into the ventricles during the early filling phase when the leaflet valves are open. In the subsequent late filling phase, further blood is actively delivered to the ventricles by contraction of the atria. In the systole that follows, blood … Diastole: Function, Tasks, Role & Diseases
Heart rate is the number of heartbeat cycles per minute, and a heartbeat cycle, also called cardiac action, includes the beating phases of systole and diastole. Systole refers to the contraction of the ventricles including blood ejection phase and diastole refers to the resting phase of the ventricles with simultaneous contraction of the atria and … Heart Rate: Function, Tasks, Role & Diseases
