Vedclass · Answer

(B) Parathyroid hormone $(PTH)$ is a peptide hormone secreted by the parathyroid gland.Its primary function is to regulate the level of calcium ions $(Ca^{2+})$ in the blood.When blood calcium levels decrease,the parathyroid gland is stimulated to secrete $PTH$.$PTH$ stimulates the process of bone resorption (demineralization) and increases the reabsorption of calcium by the kidneys,thereby increasing the calcium levels in the blood.
