These changes were found to be primarily because of changes in the rates of matrix formation and of bone resorption per unit area of forming or resorbing surfaces rather than to changes in the areas of these surfaces. This occurs when the body has insufficient calcium from an individual’s diet. What is the difference between resorption and absorption? 15, 16 because bisphosphonates are potent … The. Reabsorption vs Resorption - what is the difference. In medicine, resorption is the total or partial absorption of a normal or pathological element picked up through the lymphatic system or bloodstream. Bone resorption is the procedure that causes the blood to pick up bone tissue eliminated by cells called osteoclasts. These cells attach to the bone tissue and destroy it. Marshall, Operative Dentistry (1920) J. Due to reduced uptake of Ca in bone, increased Ca load with Background Granulocyte colony-stimulating factor (G-CSF) is an important immune factor that mediates bone metabolism by regulating the functions of osteoclasts and osteoblasts.
