The human body is a remarkable machine that performs an incredible array of functions without us even thinking about it. Every second, our heart beats around 100,000 times, pumping over 2,000 gallons of blood throughout the entire circulatory system. Meanwhile, our lungs expand and contract roughly 20,000 times per day, taking in oxygen and expelling carbon dioxide. Our brain processes an astonishing amount of information every minute, handling everything from complex thoughts to simple reflexes. And all this happens without us even noticing it, making the human body a truly amazing machine.
