lymph node

This term is primarily used in medical and biological contexts to describe the specialized organs of the immune system. In a clinical setting, it is frequently paired with adjectives like swollen, enlarged, or tender to indicate an active immune response or pathology.

While the term is technical, it is commonly used in patient-doctor communications. It refers to a specific anatomical structure, and its plural form is used when discussing the lymphatic network as a whole or multiple sites of inflammation.
