A typical human contains 5.00 L of blood, and it takes 1.00 min for all of it to pass through the heart when the person is resting with a pulse rate of 76.0 heartbeats/ minute. On the average, what volume of blood, in (

a. liters and (
b. cubic centimeters, does the heart pump during each beat?

Final answer:

The heart pumps approximately 0.0658 liters or 65.8 cubic centimeters of blood during each beat, given a total blood volume of 5.00 liters and a resting pulse rate of 76.0 beats per minute.

Step-by-step explanation:

When calculating the volume of blood pumped by the heart during each beat, we use the total volume of blood and the number of heartbeats per minute. With a given blood volume of 5.00 liters and a resting pulse rate of 76.0 beats per minute, we can determine the volume per heartbeat both in liters and cubic centimeters (cc or cm³).

To calculate the volume per beat:
Volume per beat (in liters) = Total blood volume / Heartbeats per minute
Volume per beat (in liters) = 5.00 L / 76.0 beats/min
Volume per beat (in liters) = 0.0658 liters

This volume can be converted to cubic centimeters, remembering that 1 liter is equivalent to 1000 cubic centimeters:
Volume per beat (in cm³) = Volume per beat (in liters) × 1000
Volume per beat (in cm³) = 0.0658 L × 1000
Volume per beat (in cm³) = 65.8 cm³

Therefore, the heart pumps approximately 0.0658 liters or 65.8 cubic centimeters of blood during each beat.
