Answer 1

Bones require a rich blood supply network so that the requisite oxygen and nutrients is supplied as well as the carbon dioxise , acid and waste metabolic products are eliminated.The vascularization of bone enables rapid growth, remodelling (including mechanical responsiveness) that is not possible in cartilage, which is essentially avascular.
