Gastric lymph nodes

Gastric lymph nodes are a group of lymph nodes that are located in the stomach. They play a crucial role in the immune system, helping to filter out harmful substances and produce white blood cells to fight off infections.

Etymology

The term "gastric" comes from the Greek word "gaster," which means stomach. The term "lymph node" comes from the Latin word "lympha," which means water, and the Greek word "node," which means knot.

Anatomy

The gastric lymph nodes are divided into two main groups: the superior gastric lymph nodes and the inferior gastric lymph nodes. The superior gastric lymph nodes are located along the lesser curvature of the stomach, while the inferior gastric lymph nodes are located along the greater curvature.

Function

The primary function of the gastric lymph nodes is to filter lymph, a clear fluid that contains white blood cells, before it returns to the bloodstream. This helps to remove harmful substances, such as bacteria and viruses, from the body. The gastric lymph nodes also produce white blood cells, which are essential for fighting off infections.
