The Lymphatic System
What is it?
The lymphatic system is a system of thin tubes and lymph nodes that run throughout the body. These tubes are called lymphatic vessels and work as a drainage system. They absorb and remove debris that are too large to enter the venous system. The lymph vessels transport this fluid via lymph nodes which act as filters. Vessels join bigger collectors and follow lymphatic pathways to finally drain back into the subclavian vein. This junction is located above the collarbone. The fluid called lymph joins the bloodstream where it is finally expelled as gas waste from the lungs.
Why do we need it?
This effective drainage system prevents fluid from building up, stagnating and causing swelling in our body. The lymph system is also an important part of our immune system. It plays a role in fighting bacteria and other infections and destroying old or abnormal cells. The body’s defense cells are located in our lymph nodes. These lymphocytes, when sensitized by infectious antigens, either act directly on the antigen or become plasma cells and form antibodies.
What happens when there’s no flow?
Initially, when the lymphatics are damaged, there is a backup of fluid in the tissue. At first, this build-up of plasma, protein, lipids and cells may not cause any symptoms. Eventually, the body responds to the abnormal backlog of lymph with swelling. This inflammatory process will continue unless action is taken to find a way to get rid of the excess lymph.
Lymphatic injury can modify immune responses and lead to increased fatigue, slow wound healing, digestive problems and general sluggishness.
