Duodenum intestine - Diseases

The duodenum is the first and shortest part of the small intestine, which is a long, narrow tube that connects the stomach to the large intestine. It is approximately 25-30 cm (10-12 inches) long and is located in the upper abdomen, just below the stomach and liver.

The duodenum receives partially digested food, along with digestive enzymes and bile, from the stomach and liver. These digestive juices are essential for breaking down food into smaller molecules that can be absorbed by the body.

The duodenum is divided into four parts, each of which has a specific function. The first part, called the duodenal bulb, is responsible for receiving food from the stomach and mixing it with digestive enzymes from the pancreas and bile from the liver.

The second part of the duodenum, called the descending duodenum, continues the process of digestion and absorption. The third part, called the horizontal or inferior duodenum, receives additional digestive enzymes from the pancreas and bile from the liver.

The fourth and final part of the duodenum, called the ascending or superior duodenum, is responsible for regulating the release of bile and pancreatic juice into the small intestine. It also absorbs nutrients such as iron and calcium.

Overall, the duodenum plays a critical role in the digestive process by receiving and processing partially digested food, as well as regulating the release of digestive enzymes and bile from the pancreas and liver. It is a vital part of the digestive system that is essential for maintaining overall health and wellbeing.
