Question

ALEJANDRA G MESTRES-BENIQUEZ · Accepted Answer

Final Answer : B, Explanation :  The rate of secretion of parathyroid hormone increases when serum calcium levels decrease. Parathyroid hormone (PTH) plays a crucial role in regulating calcium levels in the blood, and a decrease in serum calcium triggers its release to restore calcium balance by increasing calcium absorption from the kidneys, intestines, and bones.
