Question

Where does most nutrient absorption take place in the human digestive system?

Answer 1

Most nutrient absorption in the human digestive system takes place in the small intestine. Specifically, the small intestine is divided into three parts: the duodenum, jejunum, and ileum. While some absorption occurs in the duodenum, the majority of nutrients are absorbed in the jejunum and ileum, including carbohydrates, proteins, fats, vitamins, and minerals. The small intestine has a large surface area due to its villi and microvilli, which enhances its ability to absorb nutrients effectively.
