Cartilage has a solid and comparatively firm consistency, although it is not as rigid as bone. In adult humans it functions most importantly as a shock absorber in joints and prevents collapse ofsome tubular structures such as the airway. It also serves in the fetus as the model upon which many ofthe long bones are later built, and it allows rapid growth of these structures as they mature.
