Correct Answer: Option B

Explanation

Parathyroid hormone, secreted by the parathyroid glands, is responsible for regulating the levels of calcium and phosphate in the blood. It increases the levels of calcium in the blood by increasing its absorption from the intestines, increasing its release from the bones, and decreasing its excretion by the kidneys. It also decreases the levels of phosphate in the blood by increasing its excretion by the kidneys. Imbalances in parathyroid hormone levels can lead to a variety of conditions, including hyperparathyroidism and hypoparathyroidism.
