Two important functions of the digestive system are digestion and absorption. The nutrients that come from food are derived from proteins, fats, carbohydrates, vitamins, and minerals. These complex macromolecules must be broken down and absorbed in the gastrointestinal (GI) tract.

Nutrients, such as nitrogen (N), phosphorus (P), and carbon (C), are among the 16 chemical elements necessary for growth. Plants, microbes, animals, and organic matter are the biotic locations of nutrients. The atmosphere, water, and soil represent the abiotic locations.

Nutrients can be divided into 2 categories: macronutrients, and micronutrients. Macronutrients are those nutrients that the body needs in large amounts. These provide the body with energy (calories). Micronutrients are those nutrients that the body needs in smaller amounts.
