Lymph Node Tissue

Lymph node tissue comprises the encapsulated structures within the lymphatic system, acting as crucial sites for immune cell activation, antigen filtration, and lymph fluid cleansing. They are composed of distinct regions (cortex, paracortex, medulla) populated by diverse immune cells like B cells, T cells, macrophages, and dendritic cells. Their primary function involves filtering interstitial fluid, presenting antigens, and initiating adaptive immune responses. Enlargement of lymph nodes often indicates infection, inflammation, autoimmune disease, or malignancy, highlighting their role as immunological sentinels.
