How long does it take my heart (on average) to circulate all the blood in my body?

70ml heart volume, 72bpm = 5040ml per minute. This conveniently is approximately the total blood volume of a human giving us the answer of one minute. Obviously this varies hugely depending on heart rate and could vary slightly based on your personal cardiac output : total blood volume ratio.
