The jejunum is the middle section of the small intestine and is primarily responsible for nutrient absorption, including carbohydrates, proteins, and fats. The duodenum, ileum, and other parts of the small intestine also play a role in nutrient absorption, but the vast majority of it occurs in the jejunum.
