Bone Remodeling

_______ detects stress, fractures, or need for remodeling

Osteocytes detect stress, fractures, or need for remodeling

Osteocytes signal

• _____

• _____

• Osteoclasts

• Osteoblasts

Osteoclasts will do the process of

Resorption

Resorption of Bone

Osteoclasts will _____ bone and release ______ into the _____

Osteoclasts will break down the bone matrix and release it’s calcium phosphate into the blood

Osteoblasts will then _____ the bone matrix

Osteoblasts will then rebuild bone matrix

so bone resorption helps body reabsorb calcium phosphate from bones!

_{( body can use calcium for many things! ex. muscle contraction )}
