Parathyroid hormone (PTH) stimulates uptake of calcium into the bones (1) (and therefore osteoblast apoptosis (2)) and deportation of calcium from the bones (23), and inhibits excretion of calcium, generally increasing a low blood-calcium level. Low levels of PTH prevent bone loss.
1 Aldosterone stimulates Na + and water reabsorption from the gut, salivary and sweat glands in exchange for K 2  + . Aldosterone stimulates secretion of H + in exchange for K + in the intercalated cells of the cortical collecting tubules, regulating plasma bicarbonate (HCO 3 â) levels and its acid/base balance. (The increased potassium level works to regulate aldosterone synthesis by depolarizing the cells in the zona glomerulosa, which opens the voltage-dependent calcium channels .) The level of angiotensin II is regulated by angiotensin I, which is in turn regulated by renin, a hormone secreted in the kidneys.
