Which term describes the volume of blood ejected by the left ventricle in one minute?

The amount of blood the heart pumps from the left ventricle each minute is called cardiac output. It measures the heart’s overall pumping performance and is calculated by multiplying the heart rate by the stroke volume (the amount ejected with each beat). So CO = HR × SV. Preload is about the filling stretch of the ventricle before contraction, afterload is the pressure the ventricle must overcome to eject blood, and blood pressure is the arterial pressure, not the volume ejected per minute. In most resting adults, cardiac output falls in the range of about 4–7 liters per minute, depending on heart rate and stroke volume.
