As girth increases, bone is dissolved from the ________.
periosteal surface
endosteal surface
medullary cavity
epiphyseal plate
What is the role of osteoclasts in bone growth?

The medullary canal eventually fills with _________.
bone marrow
water
air
blood
Until when will the bone continue to grow?
