GENERAL HISTOLOGY

Detailed explanation-1: -The duodenum is the shortest section, on average measuring from 20 cm to 25 cm in length. Its proximal end is connected to the antrum of the stomach, separated by the pylorus, and the distal end blends into the beginning of the jejunum.

Detailed explanation-2: -The duodenum is a short structure ranging from 20–25 cm (8–10 in) in length, and shaped like a “C". It surrounds the head of the pancreas. It receives gastric chyme from the stomach, together with digestive juices from the pancreas (digestive enzymes) and the liver (bile).

Detailed explanation-3: -The duodenum is the first part of the small intestine (5-7 m), followed by the jejunum and ileum (in that order); it is also the widest and shortest (25 cm) part of the small intestine.

Detailed explanation-4: -Although the small intestine is narrower than the large intestine, it is actually the longest section of your digestive tube, measuring about 22 feet (or seven meters) on average, or three-and-a-half times the length of your body.

Detailed explanation-5: -Small intestines have three parts-Duodenum, Jejunum and ileum. The duodenum is short (20 to 25 centimeters long) and wider anterior part into which stomach empties. The jejunum is coiled middle part which is 0.8 to 1.5 meters in length while ileum is the longest terminal part with 3 to 3.5 meters in length.
