👉 The rest fluid, also known as lubricating or synovial fluid, is a vital component found within the joints of the human body. It acts as a cushion and lubricant, reducing friction between the bones during movement, thereby facilitating smooth and pain-free motion. This viscous fluid is produced by the synovial membranes lining the joint cavities and is essential for maintaining joint health, absorbing shocks, and nourishing the cartilage that covers the ends of bones. It plays a crucial role in joint function, especially during activities that involve repetitive motion or high impact, and its presence ensures the longevity and proper functioning of joints throughout life.
