Verified step by step guidance
1
Identify the function of each gland listed in the problem. The pituitary gland primarily regulates other endocrine glands and does not directly manage calcium levels.
Understand the role of the thyroid gland. It produces hormones like thyroxine and triiodothyronine, which regulate metabolism, but it does not directly control blood calcium levels.
Examine the adrenal gland's function. It produces hormones such as cortisol and adrenaline, which are involved in stress response and metabolism, not calcium regulation.
Focus on the parathyroid gland. It is responsible for producing parathyroid hormone (PTH), which directly regulates calcium levels in the blood by increasing calcium absorption in the intestines, reabsorption in the kidneys, and mobilizing calcium from bones.
Conclude that the parathyroid gland is the correct answer, as it specifically produces a hormone that maintains the balance of calcium in the blood.
