Explanation:

Oil in an engine lubricates the moving parts. In the body, the synovial sac contains synovial fluid which lubricates joints, similar to how oil lubricates an engine. Cartilage provides cushioning but not lubrication like oil. Tendons connect muscle to bone and ligaments connect bone to bone; neither has a lubricating function like oil.

Answer:

synovial sac
