What term describes the ongoing replacement of old bone tissue with new bone tissue?

• A. Bone Remodeling
• B. Ossification
• C. Calcification
• D. Resorption

Answer: (A)

Bone remodeling is the ongoing process that replaces old bone tissue with new bone tissue. It involves osteoclasts resorbing a portion of old bone, followed by osteoblasts forming new bone to fill the space. This cycle keeps bone strong, helps regulate calcium levels, and repairs microdamages from everyday wear. It’s different from ossification, which is bone formation during development or healing, not the constant turnover in mature bone. Resorption alone is just the removal part without the subsequent replacement. Hence, the term that describes continuous replacement is bone remodeling.
