Quizplus · Accepted Answer

During diastole the ventricles are relaxed and blood flows in from the atria through open AV valves.Blood flow from the atria occurs during diastole.Blood flow through the heart is a part of the circulatory system.Atrial contraction helps to load the ventricle quickly,but blood flow is not increased with elevated pressure.
