IMMUNOLOGY

Detailed explanation-1: -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-2: -The lymphatic system is important for the optimal functioning of our general and specific immune responses. The lymph nodes monitor the lymph flowing into them and produce cells and antibodies which protect our body from infection and disease.

Detailed explanation-3: -The tissues and organs that produce, store, and carry white blood cells that fight infections and other diseases. This system includes the bone marrow, spleen, thymus, lymph nodes, and lymphatic vessels (a network of thin tubes that carry lymph and white blood cells).
