Question

What happens to phosphorus levels when calcium levels are decreased?

a. Phosphorus levels increase
b. Phosphorus levels decrease
c. No change in phosphorus levels
d. Phosphorus levels fluctuate

Answer 1

When calcium levels are decreased, phosphate levels increase.

Step-by-step explanation:

When calcium levels are decreased, phosphate levels increase.

There is a reciprocal relationship between the concentrations of calcium and phosphate ions in plasma, so a decrease in calcium levels leads to an increase in phosphate levels.

Additionally, lowered phosphorus can make parathyroid activity more apparent, which can also contribute to an increase in phosphate levels.
