The duodenum is primarily located in the right upper quadrant of the abdomen. This section of the small intestine is the first part and is about 25-30 centimeters long, connecting the stomach to the jejunum. Given its anatomical position, the duodenum extends from the pylorus of the stomach and loops around the head of the pancreas, making its most significant portion situated in the right upper quadrant.

Understanding the anatomical layout of the abdomen is crucial in health assessments, as it aids in diagnosing conditions related to the gastrointestinal system. Conditions such as duodenal ulcers or blockages are often assessed by focusing on the right upper quadrant, further emphasizing the importance of knowing the duodenum’s location.
