HUMAN NUTRITION

Detailed explanation-1: -A long tube-like organ that connects the stomach and the large intestine. It is about 20 feet long and folds many times to fit inside the abdomen. The small intestine has three parts: the duodenum, jejunum, and ileum.

Detailed explanation-2: -The middle part of your small intestine is the jejunum. The jejunum absorbs most of your nutrients: carbohydrates, fats, minerals, proteins, and vitamins. The lowest part of your small intestine is the ileum. This is where the final parts of digestive absorption take place.

Detailed explanation-3: -The large intestine is much broader than the small intestine and takes a much straighter path through your belly, or abdomen. The purpose of the large intestine is to absorb water and salts from the material that has not been digested as food, and get rid of any waste products left over.

Detailed explanation-4: -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.
