How many liters of blood does the average adult heart pump in one day?
Answer
7,500 liters
Your fist-sized heart moves about 7,500 liters a day by recirculating the same 5 liters of blood some 1,500 times. Over an average lifetime that adds up to enough pumped blood to fill dozens of Olympic swimming pools.
