The first part of the duodenum is the most common location of ulcers since it is where the acidic chyme meets the duodenal mucosa before mixing with the alkaline secretions of the duodenum. [24] Duodenal ulcers may cause recurrent abdominal pain and dyspepsia , and are often investigated using a urea breath test to test for the bacteria, and ...
The gastroduodenal artery can be the source of a significant gastrointestinal bleed, which may arise as a complication of peptic ulcer disease.Because of its close relationship to the posteromedial wall of the second part of the duodenum, deeply penetrating ulcers or tumours of the duodenum may cause torrential bleeding from the gastroduodenal ‘artery of haemorrhage'.

The minor duodenal papilla is contained within the second part of the duodenum. It is situated 2 cm proximal to the major duodenal papilla , and thus 5–8 cm from the opening of the pylorus . The gastroduodenal artery lies posterior.
The development of the digestive system in the human embryo concerns the epithelium of the digestive system and the parenchyma of its derivatives, which originate from the endoderm. Connective tissue, muscular components, and peritoneal components originate in the mesoderm .
The enterogastric reflex is one of the three extrinsic reflexes of the gastrointestinal tract, the other two being the gastroileal reflex and the gastrocolic reflex. [1] The enterogastric reflex is stimulated by duodenal distension. [2] It can also be stimulated by a pH of 3-4 in the duodenum and by a pH of 1.5 in the
