👉 Vessel fluid, also known as synovial fluid, is a viscous, non-Newtonian liquid that lubricates and nourishes the articular cartilage within synovial joints. It acts as a shock absorber, reducing friction between the joint surfaces during movement and helps distribute loads evenly across the joint. Composed primarily of water, proteins, hyaluronic acid, and lubricin, it also provides nutrients to the cartilage cells (chondrocytes) and removes metabolic waste products. This fluid is continuously produced and replenished by the synovial membrane, ensuring joint health and smooth, pain-free movement.
