If your doctor notices a marked decrease in calcium ion levels in your blood, what gland might he suspect is not functioning properly and why?
What will be an ideal response?
The parathyroid gland normally responds to low calcium ion levels in the blood and releases PTH, which mobilizes osteoclasts to step up bone destruction, releasing more calcium into the bloodstream. If the parathyroid is not functioning properly it may release too much PTH or not respond at all, which seems to be the case here.
