10 Fast facts about the lymphatic system:

2. It is approximately twice the size of the blood circulation system and manages almost double the volume of fluid daily
3. Lymph starts its life as plasma, the watery component that makes up over half our blood volume
4. There are between 400-800 lymph nodes in the body that constantly monitor and filter the lymph to remove toxins, waste and pathogens
5. Swelling of the lymph nodes (or âglandsâ) in the neck are an indication that the body is in the throes of fighting an infection
6. It has been described as the âdistribution networkâ of the immune system and works seamlessly alongside it to fight bacteria, viruses and any other undesirables that make their way into the body
7. Far from being a âuseless, dead-end tubeâ, the appendix has recently been discovered to be part of the lymphatic system
8. The gut is lined with millions of lymphatic vessels (called lacteals) that absorb the fats and fatty acids that we ingest and transport them directly to the heart where they enter the circulatory system as fuel
9. It is considered the most important body system in Ayurvedic medicine, which considers it to be the âwater of lifeâ
10. Unlike the circulatory system, it is a one-way system and has no âpumpâ, relying on movement, gravity and breathing to keep flowing
