Which hormone regulates blood calcium levels?
Correct answer
D
Rationale
Parathyroid hormone is the correct answer. It plays a crucial role in regulating blood calcium levels by increasing calcium levels in the blood through stimulating the release of calcium from bones and enhancing calcium absorption in the intestines. Produced by the parathyroid glands, this hormone helps maintain calcium homeostasis in the body.
