Human Heart
The tireless pump that never takes a day off/Medicine & Biology
The human heart beats about 100,000 times per day, pumping roughly 7,500 liters of blood through about 96,000 km of blood vessels. It weighs about 300 grams and generates enough pressure to squirt blood nearly 10 meters. Over an average lifetime, it will beat about 2.5 billion times without maintenance, making it arguably the most reliable pump ever known.
