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.

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

According to recent studies‚ there are less than two hundred thousand cases of bone cancer per year. There are three varieties of bone cancer which are called chondrosarcoma‚ Ewing’s sarcoma‚ and osteosarcoma. The most dangerous out of the three is Ewing’s Sarcoma‚ which only seventy percent out of one hundred survive after five years of the diagnosis. Chondrosarcoma is also very dangerous if it has progressed further before treatment‚ making it only a twenty-five percent survival rate after five

There is a difference of opinion among canine experts as to whether bones should be given to a dog raw‚ cooked‚ hard‚ or soft‚ and even whether they should be given at all. On one point‚ however‚ there is total agreement‚ never give a dog splintering bones from chicken‚ pork‚ fowl‚ and rabbit‚ (although chicken bones that have been cooked in a pressure cooker until they are very soft can be quite nourishing and safe). A marrow bone is the traditional symbol of a treat for a dog‚ and he obviously appreciates
