👉 Rich fluid, also known as synovial fluid, is a vital component of the joints in the human body. It acts as a lubricant and shock absorber, reducing friction between the bones during movement and protecting joint structures from wear and tear. Composed primarily of water, hyaluronic acid, and various proteins, rich fluid also provides nutrients to the cartilage and helps maintain joint health. It plays a crucial role in facilitating smooth, pain-free motion and is essential for the overall function and longevity of joints.
