A Protector of the Bone

Cartilage is a type of connective tissue.  While it looks similar to bones, cartilage is NOT a bone!  Instead, it is its own kind of connective tissue.  It has a soft, flexible, and smooth texture.  Therefore, it has the ability to withstand collision, shock, and grinding motions.  Without its help, the bones would wear themselves out in no time and cause unbearable pain whenever you move.

With the abilities stated above, cartilage is very good at protecting bones from shock and collision.  This is also why they are often found at the two ends of a bone.  Last but not least, they end up indirectly protecting the rest of the body with their absorption of shocks in general.
