The human body is a complex and highly specialized system that has evolved over millions of years to optimize its performance. The brain, the central organ of the nervous system, controls every aspect of the body's functions, from movement to sensation to emotion. The heart, a muscular pump, circulates blood throughout the body, supplying oxygen and nutrients to tissues and organs. The lungs, responsible for respiration, extract oxygen from the air and expel carbon dioxide. The digestive system breaks down food into nutrients that are absorbed into the bloodstream, where they are transported to cells throughout the body.
