The human body is incredibly complex, comprising of numerous organs that function together to maintain life. The skin is the largest organ and serves as a protective barrier against external factors such as temperature, light, and infection. It also plays a vital role in regulating body temperature through sweating and shivering. The heart pumps blood throughout the body, supplying oxygen and nutrients to tissues while removing waste products. The lungs are responsible for exchanging gases between the air we breathe and the bloodstream, allowing us to inhale oxygen and exhale carbon dioxide. The brain serves as the central control unit, processing information from various senses and controlling voluntary movements such as walking, talking, and writing.
