Answer:
Synovial fluid functions as 1) a lubricant for your joints, it reduces friction. if it weren't for the synovial fluid we would have hot joints. 2) A shock absorber. When we move our bones bounce together, with a small amount of fluid between your joints you are reducing the amount of force placed directly on the bone. 3) Nutrient/Waste transporter. Just like the many other fluids in the human body, the synovial fluid also carries important things back and forth between different parts of the body. In this case it carries nutrients to the bones and takes away the wastes of them.
