Exempel på hur man kan använda DUODENUM i en mening

• As a part of the digestive system, it functions as an exocrine gland secreting pancreatic juice into the duodenum through the pancreatic duct.
• The duodenum is the first section of the small intestine in most higher vertebrates, including mammals, reptiles, and birds.
• The ileum follows the duodenum and jejunum and is separated from the cecum by the ileocecal valve (ICV).
• Its lining is specialized for the absorption by enterocytes of small nutrient molecules which have been previously digested by enzymes in the duodenum.
• The bile is then released via the common bile duct into the duodenum, where the bile helps in the digestion of fats.
• Secretin is a hormone that regulates water homeostasis throughout the body and influences the environment of the duodenum by regulating secretions in the stomach, pancreas, and liver.
• Chyme slowly passes through the pyloric sphincter and into the duodenum, where the extraction of nutrients begins.
• Since about 15 mmol of calcium is excreted into the intestine via the bile per day, the total amount of calcium that reaches the duodenum and jejunum each day is about 40 mmol (25 mmol from the diet plus 15 mmol from the bile), of which, on average, 20 mmol is absorbed (back) into the blood.
• Somatostatin is secreted by delta cells at several locations in the digestive system, namely the pyloric antrum, the duodenum and the pancreatic islets.
• Cholecystokinin, formerly called pancreozymin, is synthesized and secreted by enteroendocrine cells in the duodenum, the first segment of the small intestine.
• The pylorus is considered as having two parts, the pyloric antrum (opening to the body of the stomach) and the pyloric canal (opening to the duodenum).
• Its five most significant features are chronic cholestasis, a condition where bile cannot flow from the liver to the duodenum, occurring in 95% of cases; heart abnormalities (over 90%); butterfly vertebrae; posterior embryotoxon and a distinctive face (prominent forehead, deep-set eyes, and a pointed chin).
• Gastrin is a linear peptide hormone produced by G cells of the duodenum and in the pyloric antrum of the stomach.
• The pancreas further produces large amounts of bicarbonate and secretes bicarbonate through the pancreatic duct to the duodenum to neutralize gastric acid passing into the digestive tract.
• Esophagogastroduodenoscopy (EGD) or oesophagogastroduodenoscopy (OGD), also called by various other names, is a diagnostic endoscopic procedure that visualizes the upper part of the gastrointestinal tract down to the duodenum.
• Through the endoscope, the physician can see the inside of the stomach and duodenum, and inject a contrast medium into the ducts in the biliary tree and/or pancreas so they can be seen on radiographs.
• Its middle retroduodenal part is oriented inferiorly and right-ward, and is situated posterior to the first part of the duodenum, and anterior to the inferior vena cava.
• If the stomach cannot be reattached to the duodenum, a Billroth II is performed, wherein the remaining portion of the duodenum is sealed off, a hole is cut into the next section of the small intestine (called the jejunum), and the stomach is reattached at this hole.
• The complications include rupture, peripheral embolization, acute aortic occlusion, and aortocaval (between the aorta and inferior vena cava) or aortoduodenal (between the aorta and the duodenum) fistulae.
• They are most abundant near the pylorus, growing shorter and more sparse distally towards the terminal portion of the duodenum.
