Cartilage is easier to contract and expand than bone

In addition, the bones of the ribs end in cartilages [cartilagines costales] which to all practical purposes correspond to the bones; but these also have a special function of permitting the size of the thorax (which they form together with the ribs) to be more easily expanded and contracted than if they were rigid and hard like bones. Also, for a similar purpose the cartilages of the rough artery [cc. trachiales] that look like our letter C differ from bones in that besides handsomely holding it up and performing the function of support, 5 they posses that blend of properties that allows

them to be stretched and compressed unlike bone.
