A person breaks a bone and has it set and put in a cast, but it does not heal. What would be the best thing for the doctor to in
vestigate as a possible cause? The bone marrow, which should have supplied the growing bone with blood
The ligaments, which should have held the ends of the bone together while it mended
The synovial fluid in the bone, which should have carried nutrients to the growing bone
The osteoblasts, which should have been building the new bone
The osteoblasts, which should have been building the new bone
