When the body finds an infection or problem, lymphocytes within the lymph nodes multiply as well as create antibodies to fight off the invaders. Macrophages as well as dendritic cells function as scavengers, engulfing and digesting international fragments to avoid more harm.

  • Lymph nodes are an important component of the body immune system.
  • They aid filter lymph and also capture foreign compounds.

  • Malignant Lymphomas: These are cancers cells that come from the lymphatic system, commonly leading to the uncommon growth of lymphoid cells. Common kinds include Hodgkin lymphoma and also non-Hodgkin lymphoma.
