Quizplus · Accepted Answer

Synovial fluid is a clear, viscous fluid contained within the synovial cavity of movable joints. Its primary function is to reduce friction between the articular cartilage of synovial joints during movement. Mucus is a slimy substance produced by mucous membranes, which is not related to lubricating joints. Saliva is a watery fluid secreted by salivary glands, and serous fluid is a type of clear bodily fluid that fills the cavities between layers of tissues and organs in the body.
