Lymph nodes are a vital part of the body’s immune system and play a role to fight off infections. The human body has approximately 600 lymph nodes – but only in the submandibular region (the lower part of the jaw, armpits, or groin in healthy people). Lymph nodes are enclosed in fibrous capsules, which contain a collection of cells forming the immune system and are the filtering point of the antigens (foreign proteins) from the lymph vessels that pass through them.
Lymphatic vessels will collect and filter lymph nodes as it moves toward larger vessels called collecting ducts. There are many white blood cells in the lymph nodes – which can collect, interact with each other as well as antigens, and stimulate your body’s immune responses to foreign substances. Swollen or enlarged lymph nodes may indicate an infection or other medical conditions.
What are The Functions of Lymph Nodes?
Enlarged lymph nodes may be caused by multiplication of cells within the nodes, such as lymphocytes, plasma cells, monocytes, and histiocytes, or due to an entry of inflammatory cells (neutrophils) to treat infection in the lymph nodes (lymphadenitis), an influx of malignant cells, or accumulation in a macrophage model of Gaucher disease.
