Are bones composed of non living tissue?

Bones are primarily composed of living tissue, including bone cells (osteoblasts, osteocytes, and osteoclasts) that are involved in bone formation, maintenance, and remodeling. However, the bone matrix, which includes minerals like calcium phosphate and collagen fibers, provides structural support and is considered non-living. Thus, while bones have a significant living component, they also contain non-living materials that contribute to their strength and durability.
