Organs of the Immune System. The major organs of the immune system are bone marrow, thymus, spleen and lymph nodes. These organs produce lymphocytes required to destroy bacteria, virus, tumor cells, etc.This article dwells on these major immune system organs that protect the human body from infections.-Cells: The main function of T-cells or T lymphocytes is intensifying immune system responses. They do this by secreting specialized factors, which in turn activate other white blood cells, to fight off infections. T-cells are again subdivided into different types.
lymphocytes bone lymph nodes. The organs of the immune system either make the cells that participate in the immune response or act as sites for immune function.These organs include the lymphatic vessels, lymph nodes, tonsils, thymus, Peyer's patch, and spleen.The lymph nodes are small aggregations of tissues interspersed throughout the lymphatic system. White blood cells (lymphocytes) that function in the immune response are concentrated in the lymph nodes.Lymphatic fluid circulates through the lymph nodes via the lymphatic vessels. As the lymph filters through the lymph nodes, foreign cells of microorganisms are detected and overpowered.he lymph nodes are small aggregations of tissues interspersed throughout the lymphatic system. White blood cells (lymphocytes) that function in the immune response are concentrated in the lymph nodes. Lymphatic fluid circulates through the lymph nodes via the lymphatic vessels.
