3. How Do Lymph Nodes Work?
The lymphatic system runs through the entire body, much like the blood circulatory system. It collects fluid known as lymph or lymphatic fluid, and passes it through the lymph nodes.
The structure of the lymph nodes is designed to carry out filtration of lymphatic fluid and to remove pathogens and other foreign particles from the plasma. Once this is done, the filtered plasma gets back into the bloodstream through the blood vessels connected to the lymph nodes.
