Bone is a mineralized connective tissue. It contains cells that deposit collagen and release magnesium, phosphate and calcium ions that form a substance called bone mineral. It causes bone to be strong and flexible as well. In bone, there is a repeating structure called a Haversian system. This contains layers of mineralized matrix which are deposited around a central canal called the Haversian canal. Within this canal, is a nerve and a blood supply. Bone, like other tissue in the body requires oxygen as well as nutrients and waste removal. The purpose of the blood vessels is to provide those things to the bone, via the circulating blood. Bone marow, which is found within the spongy bone tissue, has the role of manufacturing new blood cells.
