What type of fluid is present at synovial joints?

Explanation:
Synovial fluid serves as the lubricating medium inside a joint. It’s produced by the lining of the joint (the synovial membrane) and fills the joint cavity to reduce friction between the articular cartilage surfaces during movement. It also provides nutrients to the avascular cartilage and acts as a shock absorber. The other fluids mentioned aren’t located in joints: aqueous humor is in the eye, serum is the liquid part of blood, and lymphatic fluid travels in the lymphatic system. Therefore, the fluid present at synovial joints is synovial fluid.
