The human body is a remarkable machine that functions seamlessly even when we are not aware of it. The brain, which weighs approximately three pounds, controls every aspect of our lives, from movement to thought and emotion. It is a complex organ that operates with incredible speed and precision, processing information in mere seconds. The heart, on the other hand, beats steadily at around 100 times per minute, pumping blood throughout the body and supplying oxygen to its various parts.
