Detailed explanation-1: -Cartilage is a strong, flexible connective tissue that protects your joints and bones. It acts as a shock absorber throughout your body. Cartilage at the end of your bones reduces friction and prevents them from rubbing together when you use your joints.

Detailed explanation-2: -Many joints have cartilage (KAHRT-uh-lij) on the ends of the bones where they come together. Healthy cartilage helps you move by allowing bones to glide over one another. It also protects bones by preventing them from rubbing against each other.

Detailed explanation-3: -Get regular exercise Regular exercise may also protect against cartilage damage. Try these exercises for joint health: Walking: Low-impact exercises like walking put less stress on your joints. The steady movement also increases blood flow, supplying your cartilage with nutrients to protect your bones and joints.

Detailed explanation-4: -Ligaments: Bands of strong connective tissue called ligaments hold bones together.

Detailed explanation-5: -Friction between the bones is reduced by a thin layer of articular cartilage covering the surfaces of the bones, and by a lubricating synovial fluid, which is secreted by the synovial membrane.
