The human body is a complex machine that is made up of trillions of cells. These cells are like individual units that work together to keep the body running smoothly. The cells in the body are like tiny factories, producing proteins and other substances that are needed for growth and repair. Just as a factory needs raw materials to produce goods, the cells need fuel to function properly. This fuel is provided by the food we eat, which is broken down into energy that the cells can use. The energy from the food is like gasoline for a car, allowing the body's systems to run efficiently.
