lymph node
LowTechnical/Medical
Definition
Meaning
A small, bean-shaped organ that filters lymph fluid and contains immune cells, part of the body's lymphatic system.
In addition to its filtering function, it serves as a site for the activation of lymphocytes (immune cells) and is a critical indicator of health, as swelling or tenderness often signals infection, inflammation, or malignancy.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque 'лимфатический узел' in overly casual speech where just 'узел' might be misunderstood as a knot or node in a non-biological sense. The standard medical term is 'лимфатический узел' or 'лимфоузел'.
- Do not confuse with 'гланды' (tonsils), which are a specific type of lymphoid tissue.
Common Mistakes
- Mispronouncing 'lymph' as /laɪmf/ (like 'lye-mf') instead of /lɪmf/ (like 'limf').
- Using 'lymph node' as a countable noun without the plural 's' when referring to multiple (e.g., 'swollen lymph node' instead of 'swollen lymph nodes').
- Confusing 'lymph node' with 'lymph vessel' or other parts of the lymphatic system.

Yes, lymph nodes are often removed surgically (lymphadenectomy) for diagnostic or therapeutic reasons, such as in cancer treatment. The body's lymphatic system can often compensate, though there is a risk of lymphedema (swelling) in the affected area.
