Approximately how many liters of blood are pumped by the heart each day?

Explanation:
The amount the heart pumps each day comes from its resting cardiac output, about 5 liters per minute. To estimate daily volume, multiply by minutes in an hour and hours in a day: 5 L/min × 60 min = 300 L/hour, and 300 L/hour × 24 hours ≈ 7,200 L/day. Rounding gives roughly 7,000 liters. So the heart moves about seven thousand liters of blood daily, with actual daily total rising during activity.
