What is the primary function of lymph nodes?

The primary function of lymph nodes is to fight pathogens because they are a key part of the immune system. This achieves several means, including removal of foreign particles from the body, creating anti-taps, producing lymphocytes and cells consuming cells known as macrophages. They are distributed throughout the body and are connected by channels known as lymphatic vessels. Lymph nodes

are very small and shaped as beans. Although spread throughout the body, they are located mainly in the neck, armpits, groin and chest. The nodes are connected by lymphatic blood vessels, which are paths that carry the lymph body. The lymph is responsible for recirculation of protein and excess fluid and for carrying bacteria to the lymph nodes to be destroyed.

probably the most important function of lymph nodes is the production of lymphocytes. Lymphocytes are specialized white cells, of which there are three types: T cells, B cells and natural killer cells. All these cells contribute to immuneBy attacking and destruction of other cells and in the case of T and B cells, they create further immunity by creating antibodies. Macrophages, other cells that are in nodes but are not created, destroy bacteria by ingestion and dissolution of enzymes, a process known as phagocytosis.

When the disease hits, lymph nodes can be the main indicator of the state of the state. If they are ignited, the amount of B cells will increase and swell. If this happens, it is generally a sign of infection or other condition of the disease.

types of diseases that affect lymph nodes differ in severity and symptoms. In the case of less infection, such as the neck infection, they will usually swell only the glands around the neck. In more serious diseases such as cancer, swollen glanding can be swollen.

With regard to cancer, lymph nodes may be an indicator of not only the presence of the disease but also the severity. Often usedThey are theatrical cancer, which means that they can indicate how much cancer has attacked the body; This is usually given by a rank from 1 to 4, with 4 the most serious.

In addition to being indicators of the disease in the body, lymph nodes can also be a disease site. One such example is Hodgkin's disease, a form of cancer. In Hodgkin, the nodes themselves are cancer. Since one symptoms of the disease are swollen lymph nodes, node biopsy is used to diagnose and distinguish from other possible causes.
