Detailed explanation-1: -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-2: -Duodenum is the smallest region of the small intestine. Jejunum is the middle part of the small intestine and mostly remains empty. Ileum is the end part of the intestine and is the largest part of the small intestine. Ileum is the connecting link between the large intestine and the small intestine.
Detailed explanation-3: -The small intestine is actually the longest segment of the gastrointestinal tract-the long, continuous pathway that food travels through your digestive system. In the small intestine, food is broken down into liquid and most of its nutrients are absorbed. The waste is passed on to the large intestine.
Detailed explanation-4: -Your small intestine makes digestive juice, which mixes with bile and pancreatic juice to complete the breakdown of proteins, carbohydrates, and fats. Bacteria in your small intestine make some of the enzymes you need to digest carbohydrates.
