The lymphatic organs can be classified into 1-primary (central) lymphoid organs, i.e., bone marrow and thymus, that produce lymphocytes and 2-secondary lymphoid organs, i.e., spleen, lymph nodes, and tonsils, that filter out and destroy undesired pathogens. The central lymphoid organs are sites where lymphocytes can divide and proliferate.
