Brunner’s Glands:
- These are present only in the duodenum.
- These are located in the submucosa.
- The main function of these glands is to produce a mucus-rich, alkaline secretion (containing bicarbonate).
- This mucus neutralizes the acidic content of chyme which is introduced into the duodenum from the stomach.
- It also provides an alkaline condition for optimal intestinal enzyme activity, thus enabling absorption to take place in the small intestine.
