Question

The average heart pumps about 80ml of Blood each contraction. if your heart rate was 70 beats per minute, calculate the volume of Blood your heart pumps in one minute when you are resting. show your calculation.
at this rate how much blood would your heart pump in one hour? show your calculation.

Answer 1

The heart beat rate is 70beats/minute with 80ml of blood pumped every beat. Then, the volume of blood your heart pumps in one minute would be:

volume of blood per minute= volume per beat * beat per minute
volume of blood per minute= 80ml/beat * 70beat/minute= 560ml/ minute

volume of blood per hour would be: 560ml/minute * 60 minute/hour= 33.600 ml/hour
