The human body is a complex machine that functions smoothly when all its parts work together in harmony. The brain is like the CEO of this machine, sending signals and instructions to different parts of the body through a network of nerves. The heart pumps blood throughout the system, supplying oxygen and nutrients to muscles, organs, and tissues. Meanwhile, the lungs take in oxygen and expel carbon dioxide, keeping the air clean and fresh inside the body.
