Each lymph node is connected to lymphatic vessels, which carry lymphatic fluid to and from the node. The vessels bring fluid right into the node, where it is filtered and processed by the immune cells. The filtered liquid after that leaves the node with one more set of vessels, which ultimately drain into bigger lymphatic air ducts that return the fluid to the blood stream.
There are numerous lymph nodes in the body, all collaborating to help protect against infection and illness. The nodes are arranged into groups or chains that are interconnected by the lymphatic vessels. This enables reliable communication and coordination in between the nodes in reacting to threats.
- Cervical lymph nodes: located in the neck
- Axillary lymph nodes: situated in the underarms
- Inguinal lymph nodes: located in the groin
- Abdominal lymph nodes: located in the abdominal area
Function of Lymph Nodes
The primary feature of lymph nodes is to filter lymphatic fluid and trap damaging materials before they can take a trip to various other components of the body. When the immune cells in the nodes run into an international intruder, such as a virus or bacteria, dianorm iskustva they create antibodies and mount an immune response to damage the danger.
