Duodenal atresia is the congenital absence or complete closure of a portion of the lumen of the duodenum. It causes increased levels of amniotic fluid during pregnancy ( polyhydramnios ) and intestinal obstruction in newborn babies.
The duodenal bulb is a remnant of the mesoduodenum, a mesentery that suspends the organ from the posterior abdominal wall in fetal life. [10] The first part of the duodenum is mobile, and connected to the liver by the hepatoduodenal ligament of the lesser omentum. The first part of the duodenum ends at the corner, the superior duodenal flexure.
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.

Normal histology of the breast, with lumen annotated at bottom right [1] In biology, a lumen (pl.: lumina) is the inside space of a tubular structure, such as an artery or intestine.

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.
English: Sequence of images diagramming the emptying of stomach chyme into the duodenum through the pyloric sphincter. As the stomach fills, signals from the stomach initiate the secretion of alkaline mucous into the duodenum. Peristaltic waves in the stomach then push chyme through the dilated pyloric sphincter into the duodenum.
Lumen also recorded a $156 million free-cash-flow loss in the quarter. And while management guided for $1.1 billion in positive free cash flow this year, $700 million of that will be due to a one ...
The junction between the foregut and midgut occurs directly below the major duodenal papilla. [3]: 274 The major duodenal papilla projects less than a centimetre into the lumen of the duodenum. [4] It appears rounded and is often covered by a fold on the uppermost side of the papilla; that is, the side which receives contents from the stomach. [4]
