Detailed explanation-1: -The first part of the small intestine. It connects to the stomach. The duodenum helps to further digest food coming from the stomach. It absorbs nutrients (vitamins, minerals, carbohydrates, fats, proteins) and water from food so they can be used by the body.
Detailed explanation-2: -The duodenal bulb, about 2 cm (3⁄4 in) long, is the first part of the duodenum and is slightly dilated. The duodenal bulb is a remnant of the mesoduodenum, a mesentery that suspends the organ from the posterior abdominal wall in fetal life.
Detailed explanation-3: -The small intestine has three parts: the duodenum, jejunum, and ileum. It helps to further digest food coming from the stomach.
Detailed explanation-4: -It may be subdivided into four sections: superior part, descending part, horizontal part and ascending part. The superior part (first part, D1) lies intraperitoneally and is enlarged proximally (duodenal bulb). It is connected to the liver by the hepatoduodenal ligament.
