Parathyroid hormone is responsible for increasing plasma Ca²⁺ levels by stimulating the release of Ca²⁺ from bones and increasing reabsorption of Ca²⁺ from urine in the kidneys. In response to the decrease in plasma Ca²⁺ levels, we would expect to see higher levels of parathyroid hormone to help bring the levels back up to normal.
