Disorders of the Lymphatic System

Abstract

The lymphatic system is the body’s cleansing and recycling service. It removes toxins, waste and recycles fat and fluid. It also forms part of our immune system. The lymphatic system provides all the checks and balances for other body systems. It is the main controller of body fluid balance and it provides immunosurveillance and is responsible for creating immunity. It mobilises fat: impaired lymph drainage results in fat deposition and lymphoedema swelling is as much fat as fluid. It is also important for preventing atherosclerosis. It patrols for cancer cells; if this surveillance fails, cancer progresses. It regulates self‐tolerance, with failure resulting in autoimmune disease.
