Answer 2

Answer:

Joints are movable connections between two bones. ... It provides a smooth surface to stop the bones in the joint from rubbing against each other too much. The cartilage passes the pressure in the joint on to the bone underneath it. This is especially important in joints that bear heavier loads, such as hip or knee joints.
