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

4900 cm3 per minute

Explanation:

70 × 70 cm3 = 4900 cm3 per minute

Cardiac output is equal to stroke volume and heart rate which means that stroke volume x heart rate = cardiac output.

In this case, stroke volume is 70 litres/minute and heart rate is 70 bpm.

Cardiac output is considering the measure of total volume that blood pumped out by the left ventricle in every minute.

stroke volume x heart rate = cardiac output

SV x HR = CO

blood alcohol concentration is affected by factors such as body size and gender.

( i saw this one before)

answer 2 is the right one. jim should measure his snack to make sure he is using the right serving size.
