The small intestine is a tube measuring about 2.5 cm in diameter. The complete small intestine is approximately 600 cm (20 feet) long and coiled in loops, which fill most of the abdominal cavity. It extends from the pyloric sphincter to the ileocecal valve, where it joins the large intestine and is comprised of three parts: Show

Most absorption of nutrients and water happen in the intestines. The intestines include the small intestine, large intestine, and rectum. The small intestine (small bowel) is about 20 feet long and about an inch in diameter. Its job is to absorb most of the nutrients from what we eat and drink. Velvety tissue lines the small intestine, which is divided into the duodenum, jejunum, and ileum. The large intestine (colon or large bowel) is about 5 feet long and about 3 inches in diameter. The colon absorbs water from wastes, creating stool. As stool enters the rectum, nerves there create the urge to defecate. Intestine Conditions

What is the average length of intestines?Research suggests that the combined length of the small and large intestines is at least 15 ft in length. The small intestine can measure about 9–16 ft, while the large intestine is roughly 5 ft long.
What is the average length and main function of the small intestine?The small intestine, or small bowel, is a hollow tube about 20 feet long that runs from the stomach to the beginning of the large intestine. The small intestine breaks down food from the stomach and absorbs much of the nutrients from the food. The duodenum is the first part of the small intestine.
