GENERAL HISTOLOGY

Detailed explanation-1: -The duodenum is the first part of the small intestine. It is located between the stomach and the middle part of the small intestine, or jejunum. After foods mix with stomach acid, they move into the duodenum, where they mix with bile from the gallbladder and digestive juices from the pancreas.

Detailed explanation-2: -The beginning portion of the small intestine (the duodenum) begins at the exit of the stomach (pylorus) and curves around the pancreas to end in the region of the left upper part of the abdominal cavity where it joins the jejunum. The duodenum has an important anatomical feature which is the ampulla of Vater.

Detailed explanation-3: -Positioned inferiorly to the stomach, the duodenum is approximately 25 to 30 cm long. Interestingly enough, this portion of the small intestine got its name due to its length. In Latin, the term “duodenum” means 12 fingers, which is roughly the length of the duodenum.

Detailed explanation-4: -Duodenum. The duodenum is the first part of the small intestine that the stomach feeds into. It’s a short, descending chute (about 10 inches long) that curves around the pancreas in a “C” shape before connecting to the rest of the coiled intestines.
