Which of the Following Antagonistic Hormones Keep the Blood Calcium

Question

Which of the following antagonistic hormones keep the blood calcium level balanced?
A)Aldosterone and cortisol
B)Parathyroid hormone and calcitonin
C)Epinephrine and norepinephrine
D)FSH and LH
E)ADH and OT

Accepted Answer

Parathyroid hormone and calcitonin are antagonistic hormones that work together to regulate blood calcium levels. Parathyroid hormone increases blood calcium levels by stimulating the release of calcium from bones and increasing calcium absorption in the kidneys and intestines, while calcitonin decreases blood calcium levels by stimulating calcium deposition in bones and decreasing calcium reabsorption in the kidneys.
