Detailed explanation-1: -The small intestine is longer than the large intestine. It has a larger surface area for absorption of nutrients from the food. The length of the small intestine is about 7.5m.
Detailed explanation-2: -The jejunum is the midsection of the small intestine, connecting the duodenum to the ileum. It is about 2.5 m (8 ft) long, and contains the circular folds, and intestinal villi that increase its surface area.
Detailed explanation-3: -The length of the small intestine is roughly 9–16 feet (ft), while the large intestine is shorter, measuring about 5 ft long. The intestines sit in the abdomen and absorb nutrients, vitamins, and water. They form part of the gastrointestinal (GI) tract and the latter section of the digestive system .
