Detailed explanation-1: -Systole (left) typically refers to ventricular systole, during which the ventricles are pumping (or ejecting) blood out of the heart through the aorta and the pulmonary veins.
Detailed explanation-2: -It returns to the heart and enters the left atrium. From there, blood is forced through the mitral valve into the left ventricle. This is the muscular pump that sends blood out to the rest of the body. When the left ventricle contracts, it forces blood through the aortic semilunar valve and into the aorta.
Detailed explanation-3: -During diastole, the build up of blood in the atria creates a pressure gradient that forces open the AV valves allowing for about 75% of this blood to pass into the ventricle causing a gradual increase in ventricular diastolic pressure (point A).
