Explanation:
Detailed explanation-1: -Cardiac output is the product of heart rate (HR) and stroke volume (SV) and is measured in liters per minute.
Detailed explanation-2: -Stroke volume is the amount of blood ejected from the ventricle with each cardiac cycle. It can be readily calculated by subtracting the end-systolic volume from the end-diastolic volume. Multiplying the stroke volume by the heart rate yields the cardiac output, typically reported in liters per minute.
