DUODENUM Meaning and Definition

  1. The duodenum is a noun that refers to a part of the small intestine, specifically the first and shortest segment. It is a hollow, tube-like structure, approximately 10 inches long, that connects directly to the stomach at one end and leads to the jejunum, the next section of the small intestine, at the other end.

    Functionally, the duodenum plays a vital role in the digestion process. Upon receiving partially digested food, bile from the gallbladder, and enzymes from the pancreas, it further breaks down the food into smaller particles and helps neutralize its acidity. The duodenum also aids in the absorption of nutrients including carbohydrates, fats, proteins, minerals, and vitamins, which are then transported to the bloodstream for distribution to the body's cells.

    Anatomically, the duodenum is divided into four parts: the superior part, descending part, horizontal part, and ascending part. These segments are positioned around the head of the pancreas, forming a C-shaped curve. The duodenal wall is lined with mucus-secreting glands, villi, and microvilli, which increase the surface area for efficient absorption.

    Overall, the duodenum serves as a crucial link between the stomach and the rest of the small intestine, contributing significantly to the digestion and absorption of nutrients.
