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: -It begins at the pylorus and ends at the ligament of Treitz and is approximately 25 cm in length. The duodenum is largely retroperitoneal and has an intimate anatomic relationship with the pancreas. It is divided into four sections: first (bulb), second (descending), third (transverse), and fourth (ascending).
