Bill is a cyclist. Before he began competing seriously, his resting heart rate was 70 bpm and
his resting stroke volume was 70 litres/minute. Calculate Bill’s resting cardiac output

The correct answer is 4900 cm3 per minute . That is Bill's resting cardiac output because in this case, we multiplied his heart rate and stroke volume.

His stroke volume was 70 liters/minute and his heart rate was 70 bpm.

Cardiac output is showing us how much is the total volume that blood pumped out by the left ventricle in a minute.

stroke volume x heart rate = cardiac output

SV x HR = CO

70 × 70 cm3 = 4900 cm3 per minute
