👉 The satisfied fluid, also known as synovial fluid, is a viscous, lubricating substance produced by synovial joints in the human body. It plays a crucial role in reducing friction between the articular cartilage surfaces during joint movement, ensuring smooth and pain-free motion. This fluid also provides nutrients to the cartilage cells and helps remove metabolic waste products, maintaining the health and integrity of the joint tissues. Additionally, it acts as a shock absorber, cushioning the joint during impact activities and contributing to overall joint stability and flexibility.
