Lymph is a watery fluid (containing white blood cells and antibodies ) that washes through all our tissues, passing through lymph node filters and eventually returning to the blood stream. Lymphatic channels are a fluid circulation system that parallel the blood circulation system. Lymphocytes wander through the lymph spaces in the body, resting and proliferating in lymph nodes . One of the typical signs of food allergy is enlarged tonsils and swollen lymph nodes in the neck. If you have an infected finger and observe a red streak going up your arm, you are seeing a lymph channel, marked by the release of inflammatory mediators . The streak reminds us that pathogenic bacteria can also travel along lymph channels and spread rapidly. If immune defense does not stop them, antibiotics are usually called for.
