Cartilage is a tough substance that forms part of the internal skeleton of animals, and is found in most vertebrates, including humans. Cartilage is flexible and wear-resistant, with qualities that can cushion shocks and protect joints. In cartilage, cells are located within the internal matrix, which is a network of proteins and polysaccharides. Thanks to the presence of cartilage, animals have strength and resilience, which helps them live and adapt to their surrounding environment.
