Upper gastric lymph nodes: anatomy and function

The lymphatic system is an important component of the body's immune system. It plays a key role in protecting the body from infections by removing harmful substances and microorganisms from tissues and organs. Lymph nodes are one of the main structures of this system, and they are located throughout the body, including the gastrointestinal tract.

The superior gastric lymph nodes, also known as lymphoglandulae gastricae superiores, are located in the upper part of the stomach. They are small oval or round formations consisting of lymphatic tissue. The gastric upper lymph nodes are located near the cardia, the junction of the esophagus and stomach. These nodes are part of the stomach's lymphatic network and have important functions in the immune system.

One of the main functions of the upper gastric lymph nodes is to filter the lymph coming from the stomach. Lymph containing harmful microorganisms, toxins and other substances passes through these nodes, where it is cleansed and disinfected. Lymph nodes contain cells called lymphocytes, which play an important role in fighting infections. They recognize and destroy pathogens, helping to strengthen the immune system.

In addition to the filtration function, the upper gastric lymph nodes also serve as a reservoir for lymphocytes. In case of infection or inflammation in the stomach area, these nodes may increase in size, indicating activation of the immune system and mobilization of lymphocytes to fight the infection.

In addition to its immune function, upper gastric lymph nodes may also be associated with certain diseases. For example, stomach cancer can spread to nearby lymph nodes, including the upper gastric nodes. This can be important in determining the stage of the cancer and developing a treatment plan.

In conclusion, the superior gastric lymph nodes are an important part of the lymphatic system of the stomach. They perform the functions of filtering, cleaning and activating the immune system in the stomach area. Understanding the anatomy and function of these nodes helps us better understand their role in maintaining health and fighting infections. Further research into the lymphatic system and its interactions with organs will allow us to better understand the mechanisms of immune defense and develop more effective treatments for various diseases associated with the stomach and lymphatic system.
