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

the aorta is the large artery leaving the heart branches into smaller arteries, which eventually branch into capillaries.the arteries carry oxygen and nutrients away from your heart, to your body's tissues. the capillaries are small, thin blood vessels that connect the arteries and the veins. the statement that arteries carry oxygen-rich blood to capillaries is true. veins on the other hand are blood vessels that take oxygen-poor blood back to the heart.

well say a good goal is to do 150 sit ups in a week! or 90 pull ups a day. even 60 push ups in a month these are all fair goals!
