The large and small intestines of the average adult human, when stretched, are only an average of 25 feet long and cannot stretch around the world. It would take the intestines of multiple humans to stretch the circumference of Earth.
Despite its name, the small intestine is the largest part of the digestive tract. Even though the small intestine is only about one inch in diameter, the small intestine is approximately 20 to 23 feet long. Because the small intestine is long, the small intestine has a lot of surface area. This large surface area helps to ensure that the nutrients are absorbed. The small intestine has three parts called the duodenum, the jejuneum, and the ileum. As mentioned previously, the duodenum begins at the pyloric sphincter. It then wraps around the head of the pancreas and ends at a turn called the duodenojejuneal flexure. It then becomes the jejuneum.
