Multiple Choice

Which hormone is secreted by the parathyroid glands, and what is its primary function?

Thyroxine; it regulates metabolism.

Insulin; it lowers blood glucose levels.

Parathyroid hormone (PTH); it increases blood calcium levels.

Calcitonin; it decreases blood calcium levels.

Verified step by step guidance

Identify the gland in question: The parathyroid glands are small endocrine glands located on the posterior surface of the thyroid gland.

Understand the primary hormone secreted by the parathyroid glands: The parathyroid glands secrete Parathyroid Hormone (PTH).

Determine the primary function of Parathyroid Hormone (PTH): PTH plays a crucial role in regulating calcium levels in the blood.

Explain how PTH increases blood calcium levels: PTH increases blood calcium levels by stimulating osteoclasts to break down bone and release calcium, increasing calcium reabsorption in the kidneys, and promoting the activation of vitamin D to increase intestinal absorption of calcium.

Differentiate PTH from other hormones mentioned: Thyroxine is secreted by the thyroid gland and regulates metabolism, insulin is secreted by the pancreas and lowers blood glucose levels, and calcitonin is also secreted by the thyroid gland but decreases blood calcium levels.
