The small intestine is a tube about 10-13 feet long folded inside the human body.
Explanation:
The small intestine connects the stomach to the large intestine (or colon) and folds many times to fit inside the abdomen. It helps in digesting food coming from the stomach. It also takes in or absorbs nutrients such as: vitamins, minerals, carbohydrates, fats, proteins and water from food so they can be useful to the body. It is made up of three areas called the duodenum, the ileum, and the jejunum.
