Which Statement Is NOT True About Parathyroid Gland Physiology

Which statement is NOT true about parathyroid gland physiology?

A) When serum calcium levels are low, PTH raises serum calcium by releasing calcium from the bone and decreasing calcium absorption in the liver.
B) The parathyroid glands maintain homeostasis of blood calcium by promoting calcium absorption into the blood and preventing hypocalcemia.
C) The parathyroid glands secrete parathyroid hormone, also called PTH or parathormone.
D) Hypercalcemia (calcium levels greater than 10.2 mg/dl in adults and 10.7 mg/dl in children) is an indication for localizing abnormal parathyroid glands.
