The lymphatic system is the most underrated part of our circulatory system. Our body contains about 50% more lymphatic fluid than blood, yet sadly many health-care practitioners rarely consider the critical role the lymphatic system plays in preventing disease and keeping us healthy.
The lymph system is the body’s primary waste elimination system and functions as the body’s primary means of immune defense. It contains over 600 “collection sites” called lymph nodes and has a network of collection vessels more extensive than the blood system. The lymph node is an immune related organ, its role is as a filtration and purification station for lymph fluid and a place for disabling and destroying bacteria, toxins, viruses, parasites, fungus, etc.
As a circulatory system, optimal flow must be maintained within the lymphatic system. Unlike the blood, whose circulation is driven by the pumping of the heart, the lymph does not have its own pump. It is propelled by three means: the movement of muscles, the nerves which create subtle pulsations, and the fluid pressure within the system. Lymph fluid is cleansed by the liver, kidneys, and heart. Therefore, physical movement and deep breathing are vital to stimulate lymphatic drainage.
The lymph fluid contains lymphocytes, these guys are like the original “Pacman” as they go about their work gobbling up all the garbage in our bodies and expelling it through the lymph system. If the lymph system is congested, the lymphocytes can’t do their job and our bodies become a virtual junk yard.
If conditions lead to sluggish lymph flow, fluid can concentrate in specific areas causing edema/swelling, or impaired function along the entire lymph system (congestion). When this state of congestion is long lasting, blockages can form and cause a backup in the flow of lymphatic fluid. Consequently, cellular waste cannot effectively be released from the body as a whole or from specific areas such as injury sites and therefore the immune system may not function at its optimum. A good analogy explaining this is whereas healthy lymph should be a thin fluid like milk, congested lymph becomes more like cottage cheese.
