Verified step by step guidance

Understand the function of synovial fluid: Synovial fluid is a viscous liquid found in the cavities of synovial joints. Its primary role is to reduce friction between the articular cartilage of synovial joints during movement.

Identify the components of synovial fluid: Synovial fluid is composed of hyaluronic acid and lubricin, which contribute to its lubricating properties. It also contains cells that help in the removal of debris and microorganisms.

Explore the anatomy of synovial joints: Synovial joints are characterized by a synovial cavity filled with synovial fluid, surrounded by a synovial membrane. This structure allows for smooth movement and flexibility.

Consider the physiological importance: Lubrication provided by synovial fluid is crucial for joint health, preventing wear and tear on cartilage and reducing the risk of joint disorders such as arthritis.

Relate to the problem statement: The correct answer to the problem is 'lubricate joints,' which aligns with the primary function of synovial fluid in maintaining joint health and facilitating movement.
