How does each hormone contribute to maintaining calcium homeostasis (be specific here)         Meaning hormone A is active under conditions of these calcium level conditions and would do a,b,c,e, f etc). Hormone          B is active under these conditions and changes calcium concentration by x,y,z. Do not forget the name the cells                      involved.  III. What is Wolffe's law of bone 

(pleаse use the cаse belоw tо аnswer the fоllowing two (2) questions) CH is a 60 year old man with stage 5 CKD and a history of calciphylaxis and uncontrolled hyperphosphatemia.  His most recent laboratory results show serum calcium of 10.0 mg/dL and a phosphorus concentration of 8.6 mg/dL. He had been receiving ergocalciferol 50,000 iu po once daily.  You cannot find a recent PTH level, therefore you order a PTH for the patient and in the meantime, try to lower his phosphorus concentration.
