Synovial fluid lubricates joints and performs other related functions. It keeps bones apart to avoid deterioration of cartilage layers and absorbs impact to shield cartilage and bones from damage. Furthermore, the substance filters nutrients for articular cartilage while preventing toxins and other harmful substances from entering the joint cavity. When joints move and bear weight, synovial fluid is squeezed out of the articular cartilage and drawn in the direction of movement to keep a layer of fluid between the cartilage surfaces.
