A thick band of bone forms around a broken bone as it heals In time the thickened band disappears Explain how this extra bone can disappear over time?

The thick band of bone that forms around a broken bone, known as a callus, is initially created to stabilize the fracture and support healing. Over time, as the bone fully heals, the body undergoes a remodeling process where excess bone is resorbed by specialized cells called osteoclasts. This process helps restore the bone's original shape and strength, allowing the thickened area to gradually diminish as the bone returns to its normal contour.
