Bone
Cancellous bone
Compact bone
Osteoblasts and osteoclasts are formed when they needed to remodel bone.
Osteoclasts remove damaged areas of bone
Osteoblasts come after them and replace the extracellular matrix.

Blood calcium is too high
Blood calcium is too low
Blood oxygen is too high
Blood viscosity is too low
Inhibits the rease of calcium from bone
Reduces osteoclast activity
Inhibits vitamin D activation in the kidney
Inhibits calcium reabsorption by the kidney
Activiates the rease of calcium from bone
Increase osteoclast activity
Activates vitamin D activation in the kidney
Increase calcium reabsorption by the kidney
