Monitoring Centers: Lymphatic system absorbs/carries things too big to go into the arteries and veins like bacteria eaten by white cells and digested food. Lymph nodes "taste" the lymph to see bacteria, viruses, cancers, etc. When it detects a problem, it alerts the immune system and enlarge in response to the inflammation they create when they react. They shrink when all is well. Persistence mandates evaluation.
