Clinical Significance
The product of the calcium and phosphate concentrations is a constant. When the level of one of these ions rises, the other must fall. These values are maintained within narrow limits by changing the rate of renal excretion. If plasma calcium falls below normal, the parathyroid gland secrets more of its hormone. This causes the kidney to excrete more phosphorus into the urine. The resulting fall in plasma phosphate allows calcium ion to move from storage deposits in bone into the plasma.
