Brunner's glands

Brunner's glands are specialized structures located in the lining of the first part of the small intestine, called the duodenum. Their main function is to produce a mucus-rich fluid that helps protect the intestinal lining from the acidic content coming from the stomach. This mucus also assists in creating a safe environment for enzymes to work and supports digestion. These glands are important for maintaining the health and function of the duodenum, ensuring that the digestive process proceeds smoothly without damage from stomach acids.
