Detailed explanation-1: -Lymph nodes and other lymphatic organs filter the lymph to remove microorganisms and other foreign particles. Lymphatic organs contain lymphocytes that destroy invading organisms.
Detailed explanation-2: -The lymphatic system also helps defend the body against germs (viruses, bacteria, and fungi) that can cause illnesses. Those germs are filtered out in the lymph nodes, small clumps of tissue along the network of lymph vessels. Inside the lymph nodes, lymphocytes called T-cells and B-cells help the body fight infection.
Detailed explanation-3: -Lymph nodes: Lymph nodes are bean-shaped glands that monitor and cleanse the lymph as it filters through them. The nodes filter out the damaged cells and cancer cells. These lymph nodes also store lymphocytes and other immune system cells that attack and destroy bacteria and other harmful substances in the fluid.
Detailed explanation-4: -Lymph nodes filter lymph via specialized white blood cells that destroy and remove microorganisms, malignant cells, damaged cells, and foreign particles.
