•The duodenum, the first part of the small intestine, aids the human body in digestion and the breakdown of food. It plays a vital role in the breakdown of chyme from the stomach, allowing for absorption of food in the small intestine.

•The duodenum is located distal to the pyloric sphincter and stomach.

•The duodenum is functionally and structurally important for the survival of the human. It is characterized as being the widest and shortest part of the small intestine2. Further, the duodenum contains the major and minor papilla, through which secretions from nearby organs are deposited.

•The purpose of our research was to measure the distance from the pylorus to the major papilla and the distance from the minor papilla to the major papilla.

•Having a solid understanding of these distances is of great importance to gastrointestinal (GI) doctors as they investigate the pathways through which bile and pancreatic juices pass upon their final draining into the duodenum. These measurements can be used for future medical studies in medicine and to allow for a better understanding of anatomical variations that occur within the small intestine.
