Lymph nodes contain several important protective cells, primarily lymphocytes, which include T cells and B cells. T cells play a crucial role in cell-mediated immunity, recognizing and destroying infected or cancerous cells, while B cells are responsible for antibody production to neutralize pathogens. Additionally, macrophages and dendritic cells present in lymph nodes help to engulf pathogens and activate lymphocytes, further enhancing the immune response. Together, these cells coordinate the body's defense against infections and diseases.
