What is the function of synovial fluid?

The function of synovial fluid is to lubricate joints and reduce friction. This viscous fluid is found in the synovial cavities of joints, such as the knees, elbows, and hips. Its primary role is to provide a smooth, slippery surface that allows the articulating bones to glide against each other with minimal resistance during movement. This lubrication is crucial for joint function, as it helps decrease wear and tear on the cartilage that covers the ends of the bones. Additionally, synovial fluid serves as a shock absorber, distributing pressure across the joint and contributing to overall joint stability. This unique combination of lubrication and cushioning makes synovial fluid essential for maintaining healthy and functional joints.
