The contraction of the left ventricle required to shoot blood out of the aorta is known as which term?

Afterload is the pressure the left ventricle must overcome to eject blood into the aorta. It represents the resistance the ventricle must push against, mainly the aortic systolic pressure and systemic vascular resistance. When afterload is higher, the ventricle must generate more force during systole to open the aortic valve and push blood out, which can reduce stroke volume if contractility or preload don’t compensate. This concept is different from cardiac output, which is the amount of blood pumped per minute, and from legal terms like standard of care or implied consent, which are not physiological.
