Question

At a resting pulse rate of 75 beats per minute, the human heart typically pumps about 73 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?

Answer 1

There is approximately 5.475 liters of blood in the body.

Explanation:

At a resting pulse rate of 75 beats per minute, the human heart typically pumps about 73 ml of blood per beat.

73 ml in liters =
`73*0.001=0.073` liters

Now, 75 beats/min x 0.073 liters/beat = 5.475 liters/min

And 5.475 liters/min x 1 min/body = 5.475 liters/body

Hence, there is approximately 5.475 liters of blood in the body.
