What is the distal duodenum?
Then, what is the duodenum and what does it do?
Duodenum. The duodenum is the first and shortest segment of the small intestine. It receives partially digested food (known as chyme) from the stomach and plays a vital role in the chemical digestion of chyme in preparation for absorption in the small intestine.
Subsequently, question is, what is the 2nd part of the duodenum? The second part, or descending part, of the duodenum begins at the superior duodenal flexure. It goes inferior to the lower border of vertebral body L3, before making a sharp turn medially into the inferior duodenal flexure, the end of the descending part.
Then, what are the 4 parts of the duodenum?
The duodenum is described as having four parts:
- Part one, superior part (SD)
- Part two, descending part (DD)
- Part three, horizontal part (HD)
- part four, ascending part (AD)
What causes inflammation of the duodenum?
Duodenitis is inflammation occurring in the duodenum, the beginning of the small intestine. Severe illness and prolonged use of medications such as nonsteroidal anti-inflammatory drugs (NSAIDs), alcohol, or tobacco may also lead to duodenitis. Less commonly, Crohn's disease can cause duodenitis.
