The function of synovial fluid is
Correct answer: A. to lubricate the joint and nourish the articular cartilage
- A. to lubricate the joint and nourish the articular cartilage
- B. to produce red blood cells
- C. to store calcium for the body
- D. to carry nerve impulses across the joint
Explanation
Synovial fluid is secreted by the synovial membrane into the joint cavity, where it reduces friction between the cartilage surfaces and absorbs shock, and since articular cartilage has no blood supply the fluid also delivers its oxygen and nutrients. Red cell formation happens in red bone marrow and calcium is stored in the bone matrix, neither of which is a role of the fluid.
