The main function of the lymph nodes

Lymph nodes are important for the proper functioning of the immune system, acting as filters for foreign particles and cancer cells.

Ensure the functioning of the immune system.

Explanation:

The main function of lymph nodes is to ensure the functioning of the immune system. Pathogens or germs can cause infections anywhere in the body. Upon detection, lymphocytes, a type of white blood cell, gather with the antigens or proteins in the peripheral lymphoid organs, which include the lymph nodes. Antigens are identified by cells specialized in the lymph nodes. Naive or virgin lymphocytes (ie cells that have not yet found an antigen) enter the lump from the bloodstream through specialized capillary venules.
