Question

Quizplus · Accepted Answer

Bone remodeling helps in the maintenance of adequate concentrations of calcium and phosphate in our blood. Osteoblasts are bone-forming cells, while osteoclasts are bone-resorbing cells. If osteoblasts are more active than osteoclasts, more bone will be formed than resorbed, which is the opposite of option A. Option B is incorrect as osteoblasts function to form new bone, not break down bone. Option D is incorrect as bone remodeling rates vary depending on the location and type of bone tissue.
