Brunner S Glands

Brunner's glands (Brunner S Glands) are an important component of the digestive system, located in the small intestine and upper jejunum. They were named after the Swiss anatomist and physiologist Johan Conrad Brunner, who first described their structure in 1687.

Brunner's glands are located in the submucosa of the intestinal wall and include deep tubular glands consisting of secretory cells. They produce mucus, which plays an important role in protecting the surface of the intestinal wall from the action of food enzymes and acid, and also provides lubrication for the easy movement of bolus food through the intestines.

The Brunner's glands also produce secretions containing various factors, such as bicarbonates, which help maintain optimal pH balance in the intestines. They also secrete enzymes such as enterokinase, which help break down proteins and improve digestion.

The discovery of tumors in Brunner's glands is rare but can lead to various diseases such as adenomas, carcinomas and lymphomas.

Brunner's glands are of great importance in the human digestive system and their presence allows you to effectively digest food and absorb nutrients. Although they are rarely susceptible to disease, any disruption to their functioning can lead to serious problems with digestion and overall health.



The glands of the small intestine, also known as Brunner's glands, are one of the most important components of the human gastrointestinal tract. They are located in the duodenum (the first part of the small intestine) and the upper jejunum (the second part of the small intestine).

Brunner's glands are small glands located in the submucosa of the small intestine. They produce special mucus that protects the intestines from damage and infections. This mucus also aids in the digestion process by binding nutrients to water and facilitating their passage through the intestines.

The importance of Brunner's glands is that they help maintain intestinal health. If the Brunner's glands do not function properly, it can lead to various intestinal diseases such as ulcers, gastritis and others. In addition, a lack of mucus can lead to indigestion and poor absorption of nutrients.

In order for the Brunner's glands to function properly, you need to monitor your diet and lifestyle. A healthy diet should contain enough fiber and fluids, and avoid drinking alcohol and smoking. Regular exercise can also help maintain a healthy gastrointestinal tract.



Brunner's glands are located in the small intestine, at the junction between the duodenum and jejunum. They are located in the submucosal layer and produce mucus, which protects the intestinal mucosa from the effects of digestive juices and bacteria.

Brunner's glands are part of the human digestive system and are involved in the process of digesting food. The mucus produced by the glands protects the intestinal mucosa from irritation and damage, and also facilitates the passage of food through the intestines.

The number of Brunner's glands can vary between individuals, but they are usually present in numbers of 5 to 10 for every meter of intestinal length. These glands are about 1-2 millimeters in size and are located along the entire length of the small intestine.

Some people may have a deficiency of Brunner's glands, which can lead to various gastrointestinal diseases. For example, people with Brunner's gland deficiency may experience symptoms such as nausea, vomiting, diarrhea, and abdominal pain.

However, in general, Brunner's glands play an important role in human digestion and health. They help protect the lining of the small intestine from damage and promote proper bowel function. Therefore, it is necessary to monitor their health and maintain their normal functioning.
