The Small Intestine Facts

The small intestine is a long, coiled tube that forms the majority of the digestive system. It is responsible for the final stages of digestion and absorption of food. The small intestine is divided into three sections: the duodenum, the jejunum, and the ileum.

The duodenum is the first section of the small intestine. It is located just below the stomach and is about 12 inches long. The duodenum is responsible for the initial digestion of food. It contains digestive enzymes that break down food into small pieces.

The jejunum is the second section of the small intestine. It is located between the stomach and the ileum and is about 8 feet long. The jejunum is responsible for the absorption of nutrients from food.

The ileum is the third and final section of the small intestine. It is located between the jejunum and the large intestine and is about 10 feet long. The ileum is responsible for the absorption of water and minerals from food.

The small intestine is a vital part of the digestive system. It plays a key role in the absorption of food and the absorption of nutrients. Without the small intestine, the body would not be able to digest food and would not be able to absorb the nutrients from food.
