DUODENA Meaning and
Definition
-
Duodena is the plural form of the word "duodenum," a term used in anatomy to refer to a specific part of the small intestine. The duodenum is the first and shortest portion of the small intestine, measuring about 25-30 centimeters in length. It connects the stomach to the jejunum, the next section of the small intestine.
The duodenum plays a crucial role in the digestive process. It receives partially digested food, known as chyme, from the stomach through the pyloric sphincter. Here, the chyme is further broken down by digestive enzymes secreted by the pancreas and bile produced by the liver. These digestive substances enter the duodenum through the pancreatic and bile ducts.
The lining of the duodenum is composed of tiny finger-like projections called villi, which increase the surface area for nutrient absorption. Nutrients, such as carbohydrates, proteins, and fats, are absorbed here and transported through the bloodstream to be used by the body.
The duodenum is also responsible for regulating the emptying of the stomach, allowing the chyme to enter the small intestine at a controlled rate. It accomplishes this through the release of hormones that communicate with the stomach and other digestive organs.
In summary, the duodenum is the initial section of the small intestine that receives partially digested food from the stomach. It further breaks down the chyme and absorbs nutrients through its specialized lining, playing a vital role in the digestive process.
