Unlike the cardiovascular system the lymphatic system is not a closed system – and in humans it does not have a pump. This means that the movement of the lymph fluid relies on the physical movement of the body in order to circulate and prevent the nodes and ducts from becoming blocked with dead white blood cells.
Without adequate movement of the fluid, lymph nodes can become infected and disturb the normal homeostasis in the body’s immune and vascular systems. In the brain, a lack of lymph drainage can damage memory and contribute to Alzheimer’s disease. The same thing happens when the lymph nodes near our major organ systems don’t flow and drain effectively – it can cause widespread organ dysfunction.
