Which immune cells are white blood cells produced in lymph nodes for immunity?

Lymphocytes are the white blood cells central to immunity and the cells most closely associated with lymph nodes. They include B cells, which make antibodies, and T cells, which coordinate cell‑mediated responses. Lymph nodes serve as hubs where lymphocytes meet antigens carried by lymph, become activated, proliferate, and orchestrate targeted immune responses. Macrophages are also present in lymph nodes but come from bone marrow–derived monocytes and act as phagocytes and antigen-presenting cells, not the primary cells produced in the nodes for immunity. Lymph is the fluid that circulates through the lymphatic system, and lymph ducts are the vessels carrying that fluid. Therefore, the correct choice is lymphocytes.
