So these osteoclasts children in red are activated, they're recruited and eventually they bind. They attach onto the surface of this section, as shown in this diagram. And as soon as the osteoclast attach, they begin the process of resorbing. So they basically resorb our bone. They break down the bone and release these constituents, such as calcium and phosphate, into our bloodstream. So once resorption actually takes place and once we break down the bone, the matrix, what happens is these cells basically depart, they detach and move away while the osteoblasts shown in blue are now recruited and activated.
