Detailed explanation-1: -Duodenum. The duodenum is the first part of the small intestine that the stomach feeds into. Jejunum. The remaining small intestine lays in many coils inside the lower abdominal cavity. Ileum. The ileum is the last and longest section of the small intestine.

Detailed explanation-2: -The jejunum and ileum come from the midgut, whereas the duodenum derives from the foregut. Villi and crypts make up the lining of the small intestine. Originally, the small intestine is lined by cuboidal cells up until the ninth week of gestation; then, villi begin to form.

Detailed explanation-3: -The small intestine consists of three parts. The first part, called the duodenum, connects to the stomach. The middle part is the jejunum. The third part, called the ileum, attaches to the colon.

Detailed explanation-4: -The small intestine has three parts: the duodenum, jejunum, and ileum. It helps to further digest food coming from the stomach. It absorbs nutrients (vitamins, minerals, carbohydrates, fats, proteins) and water from food so they can be used by the body. The small intestine is part of the digestive system.

Detailed explanation-5: -Digestion and absorption The duodenum accomplishes a good deal of chemical digestion, as well as a small amount of nutrient absorption (see part 3); the main function of the jejunum and ileum is to finish chemical digestion (enzymatic cleavage of nutrients) and absorb these nutrients along with water and vitamins.
