The blood is distributed throughout the body, releasing oxygen to the cells and picking up carbon dioxide. Blood then returns to the right atrium through the veins, completing a circuit called systemic circulation.

The volume of blood that is pumped out … WebAortic pressure during diastole is usually 60-90 mm Hg (afterload). This is the pressure the left ventricle must overcome to open the aortic valve and eject blood into the aorta. The pressure gradient of systolic 100-140/60-90 mm Hg drives blood into the aorta and onward to the rest of the body. The cycle is complete.

WebESV is the measure of the blood volume that remains in the left ventricle after systole, where the blood is ejected from the heart into circulation. Afterload is a measure of the pressure present in the aorta that the left ventricle must overcome to open the aortic valve and eject the blood from the heart. WebThe left ventricle is the heart's main pumping chamber. It pumps oxygen-rich blood up into the body's main artery, called the aorta. The blood then goes to the rest of the body. A left ventricle (LV) ejection fraction of about 50% to 70% is categorized as normal.

WebThe pressure within the aorta and arterial system is called the after load. To eject blood, the heart develops pressure equal to or greater than the after load. Hydrostatic pressure is that which is exerted on the walls of the vessel by the fluid within the vessel. The rapid ejection of blood into the aorta can be felt as a pulse (pressure wave). WebThe force that is applied to the volume of blood is the intraventricular pressure. Therefore, ventricular stroke work can be estimated as the product of stroke volume and mean …
