Ib yam li ntawd, thaum cov ntshav calcium uas tsawg dhau lawm osteoclast kev ua haujlwm nce ntxiv? Parathyroid hormone (PTH), secreted los ntawm cov qog parathyroid, yog lub luag haujlwm rau kev tswj hwm ntshav calcium ntau ntau ; nws tawm thaum twg los tau ntshav calcium ntau ntau yog qis . PTH nce cov ntshav calcium los ntawm stimulating osteoclasts , uas zom cov pob txha kom tso tawm calcium rau hauv ntshav ntws.
Tom qab ntawd, lo lus nug yog, yuav muaj dab tsi tshwm sim thaum cov ntshav calcium ntau ntau poob?
