Their main function is to secrete alkaline (bicarbonate-containing) mucous in order to:[citation needed]
- protect the duodenum from the acidic content of chyme (which enters the duodenum from the stomach),
- provide an alkaline environment which promotes the activity of intestinal enzymes,
- lubricate the intestinal walls.
They are the distinguishing feature of the duodenum, and are named for the Swiss physician who first described them, Johann Conrad Brunner.[citation needed]
