The primary function of the small intestines is to carry out chemical digestion and absorption of nutrients that the body needs. This is where the majority of nutrient absorption takes place, including proteins, carbohydrates, fats, vitamins, and minerals. The small intestines also play a role in the mechanical digestion of food particles by mixing and moving them along the digestive tract.
