👉 The s-fluid, also known as synovial fluid, is a viscous, clear liquid produced by the synovial membranes lining the joints in the human body. This fluid serves multiple crucial functions: it lubricates the joint surfaces to reduce friction during movement, nourishes and protects the cartilage that cushions the ends of bones, and helps remove waste products from the joint tissues. Its composition includes water, hyaluronic acid, proteins, and various nutrients, all contributing to maintaining joint health and facilitating smooth, pain-free motion.
