The Function of Brunner's Glands in the Small Intestine
Brunner's glands are specialized structures in the duodenum that secrete an alkaline liquid containing mucin that counteracts the acidity in stomach contents. This protects the duodenum and the rest of the small intestine from acidic injury. The secretion from Brunner's glands contains bicarbonates, which have the necessary alkalinity to help increase absorption.
Brunner's glands also secrete a mucus substance that coats the intestinal walls to help food move through it smoothly. Unique to mammals, Brunner's glands also provide active and passive immune defense mechanisms.3’Krause W.
