The human body is a complex and intricate machine, composed of trillions of cells that work together to maintain life. The heart pumps blood through vessels, supplying oxygen and nutrients to tissues, while the brain processes information and controls movement. Organs such as the liver, kidneys, and lungs perform specific functions, each critical to overall health. Even the smallest components, like hair follicles and sweat glands, play a vital role in regulating body temperature and maintaining skin integrity.
