The human body is an intricate machine that operates on a delicate balance of systems and processes, each one working together to maintain life and function. The brain, the central hub of the body, controls every aspect of physical activity, from movement to digestion, through a complex network of neurons and electrical impulses. The heart pumps blood throughout the body, supplying oxygen and nutrients to cells and organs, while the lungs breathe in oxygen and exhale carbon dioxide. The immune system protects the body from disease and infection by producing antibodies that recognize and attack foreign invaders. Nerves transmit signals between the brain and other parts of the body, allowing for communication and coordination of movement.
