The duodenum precedes the jejunum and ileum and is the shortest part of the small intestine. In human beings, the duodenum is a hollow jointed tube about 25–38 centimetres (10–15 inches) long connecting the stomach to the middle part of the small intestine. [4] [5] It begins with the duodenal bulb and ends at the suspensory muscle of ...
The small intestine or small bowel is an organ in the gastrointestinal tract where most of the absorption of nutrients from food takes place. It lies between the stomach and large intestine, and receives bile and pancreatic juice through the pancreatic duct to aid in digestion. The small intestine is about 5.5 metres (18 feet) long and folds ...
A superior and an inferior duodenal recess may be created by horizontal peritoneal folds. [2] A retroduodenal recess may occur posterior to the duodenojejunal flexure. [2] The small intestine may herniate (a condition known as an "internal hernia") into these recesses, and such hernias may then strangulate. [3]

In human anatomy, the intestine (bowel or gut; Greek: éntera) is the segment of the gastrointestinal tract extending from the pyloric sphincter of the stomach to the anus and as in other mammals, consists of two segments: the small intestine and the large intestine. In humans, the small intestine is further subdivided into the duodenum ...
The cecum is a pouch marking the division between the small intestine and the large intestine. It lies below the ileocecal valve in the lower right quadrant of the abdomen. [33] The cecum receives chyme from the last part of the small intestine, the ileum, and connects to the ascending colon of the large intestine. At this junction there is a ...
The duodenum receives excretions from various organs such as the pancreas and spleen. The pancreas produces the hormone insulin, which helps regulate blood sugar. [4] [5] The second part is the jejunum, which is located in the middle of the small intestine. The final part of the small intestine is the ileum, which leads into the large intestine ...
The horizontal part of the duodenum slopes upwards to the left of the vertical midline, following which the vertical ascending part of the duodenum reaches the transpyloric plane. [6] It ends in the duodenojejunal junction, which lies approximately 2.5 cm to the left of the midline and just below the transpyloric plane. [1]
