Cartilage and bone are both stiff connective tissues which form an essential structural component of the body of animal organisms‚ including human beings. However‚ they are also quite different in both composition and function. Bones are extremely hard‚ dense tissue which provide a supportive frame for the body ‚ as well as serving as production and storage centers for cells and minerals‚ whereas cartilage is a more flexible tissue found in more specific locations of the body‚ essentially midway

Chemical Composition of Bone Bone is a very hard material which is capable of bearing a large amount of weight and resisting tension and twisting forces. Therefore‚ this material is both flexible and hard. The hardness of bone is due to calcium deposits in the matrix while the flexibility comes from the organic material of the matrix. We can illustrate these facts by treating two bone samples by two different methods: 1. Soaking a bone in vinegar (dilute acetic acid) removes calcium

up of cartilage and bone. Both bone and cartilage are connective tissues‚ that is‚ they are composed of cells in a matrix with intracellular fibers. Just imagine connective tissue as a gelatin salad with grapes and coconut. The grapes would represent cells‚ the gelatin the support material for matrix‚ and the pieces of coconut the intracellular fibers. By changing the amounts of each ingredient and adding extra substances‚ we can produce a material that is very hard like bone and can withstand weight
