Bones are composed of only dead or dormant cells. b. Haversian canals are bone structures that contain blood vessels that provide materials for the osteocytes. c. Osteocytes have membrane extensions that protrude from bone and allow them to exchange materials with the surrounding fluids. d. Bones are hollow in the middle and the low pressure there draws fluid from the blood that nourishes the osteocytes.arrow_forwardOne of the special qualities of vertebrate bone is that it is a living tissue that permits continuous remodeling.
