👉 Performed fluid, often referred to as synovial fluid, is a viscous, lubricating substance found within the cavities of joints. It plays a crucial role in joint health by reducing friction between the articular cartilage surfaces, allowing for smooth and pain-free movement. Composed primarily of water, proteins, hyaluronic acid, and various nutrients, this fluid also helps to nourish the cartilage, remove metabolic waste, and maintain joint lubrication. Synovial fluid is produced by the synovial membrane lining the joint capsule and is replenished continuously, ensuring optimal joint function and mobility.
