Describe the three functions of synovial fluid in a synovial joint
What will be an ideal response?
Synovial fluid 1 ) provides lubrication, 2 ) performs metabolic functions, and 3 ) absorbs shock. First, synovial fluid lubricates the joint cavity and articulating surfaces to reduce friction. Second, synovial fluid supplies nutrients such as glucose and removes metabolic wastes formed by cells in the joint cavity. This is a critical function since the joint cavity is not directly connected to blood vessels. Third, synovial fluid evenly distributes force and stress exerted on the articular surfaces of the bones during movement.
