Importance and Overview of the Lymphatic System
The lymphatic system is absolutely essential for immediate and long-term health and requires support. Despite its crucial role, the lymphatic system does not receive as much attention as the cardiovascular system, brain and nervous system, or even the gut microbiome.
Structure, Function, and Drainage
The lymphatic system functions as a necessary "third system" because the blood circulatory system is not perfect. After the arterial system delivers oxygenated blood, nutrients, and water to the tissues, and the venous system collects deoxygenated blood and some waste, about 3 to 4 litres of excess fluid and cellular waste products remain in the interstitial (extracellular) space.
- Function: The lymphatic system is responsible for taking this remaining fluid ("lymph") and "gunk" (proteins, ammonia, carbon dioxide, cellular waste) and bringing it back to the blood supply.
