👉 Ser fluid, also known as synovial fluid, is a viscous, lubricating substance found within the cavities of joints in the human body. It plays a crucial role in reducing friction between the articular cartilage surfaces of bones during movement, thereby facilitating smooth and pain-free motion. This fluid also acts as a shock absorber, distributing the load across the joint and protecting the underlying bone from wear and tear. Additionally, ser fluid contains nutrients that nourish the cartilage and helps in the removal of metabolic waste products, ensuring joint health and functionality.
