E)heart rate x blood pressure

Question

Cardiac output is the volume of blood pumped by the heart per unit time. It is calculated by multiplying the stroke volume (the volume of blood ejected from the heart with each contraction) by the heart rate (the number of times the heart beats per minute). The equation for cardiac output is therefore CO = SV x HR. Option A is the only choice that correctly represents this equation by expressing the stroke volume as EDV (end-diastolic volume) minus ESV (end-systolic volume).
