Question

At a resting pulse rate of 77 beats per minute, the human heart typically pumps about 71 mL of blood per beat. Blood has a density of 1060 kg/m3. Circulating all of the blood in the body through the heart takes about 1 min for a person at rest. Approximately how much blood is in the body? volume of blood in body: m3 On average, what mass of blood does the heart pump with each heart beat? mass per heart beat: kg

Answer 1

Answer:

Given:

1 minute circulation

77 beats per minute

65 ml of blood per beat

blood density of 1060kg/m³

a) how much blood is in the body?

77 beats per min * 65ml per beat = 5,005 ml per minute

5,005ml * 1l/1000ml = 5.0005 Liters.
