Understanding Cartilage Function in Joints
Imagine your joints as hinges in a door. Cartilage is like a soft cushion that prevents bones from grinding against each other. It allows smooth movement and absorbs the shock of everyday activities.

This material reduces friction between bones and distributes pressure evenly, which is essential for long-term joint health.
