The digestive system is a group of organs that work together to change the food you eat into the energy and nutrients your body needs. After you consume food and liquids, the digestive system breaks them down into their basic parts: carbohydrates, proteins, fats, and vitamins. These basic nutrients are then absorbed into the bloodstream, which carries them to cells throughout the body. Nutrients provide the cells with the energy they need for growth and repair. Everything in your body, from your hormones to your heart, needs the nutrients from the digestive process to work correctly.
