Lymph nodes are secondary lymphoid organs. Explain the role of lymph nodes in our immune response.

(N/A) Lymph nodes are small,solid structures located at different points along the lymphatic system.
Lymph nodes trap microorganisms or other antigens that enter the lymph and tissue fluid.
Antigens trapped in the lymph nodes are responsible for the activation of lymphocytes present there,which leads to the production of antibodies.
This process initiates the immune response.
Additionally,they help in destroying cancer cells.
