1. What is the classification?Secondary lymphoid organs of the immune system
2. What are lymph nodes and why are they important?Lymph nodes are tiny, bean‑shaped organs that sit along the body’s lymph vessels. They act like detectives, catching germs and other bad things from the fluid that flows through them, so the immune system can fight infections.
3. How do lymph nodes help our body fight germs?Inside a lymph node, special cells called B cells and T cells meet the germs that have been captured by other cells. The B cells make antibodies and the T cells help coordinate the immune response, so the body can quickly attack the germs.

Secondary Lymphoid Organs: Organs where lymphocytes encounter antigens and initiate adaptive immune responses, like lymph nodes and spleen.
Antigen-Presenting Cells (APCs): Cells like dendritic cells and macrophages that capture and present antigens to lymphocytes.
Lymphadenopathy: Enlargement of lymph nodes, often indicative of an underlying pathological process such as infection or malignancy.
