question 17 (2 points)
what is the primary function of the parathyroid gland?
○ to maintain the calcium - phosphorus balance

Explanation:

Question 16

The hypothalamus secretes releasing and inhibiting hormones that control the pituitary gland. The thyroid, parathyroid, and adrenal glands have other primary functions and do not control the pituitary.

The parathyroid gland's main role is to regulate calcium and phosphorus levels (balance) in the blood. Regulating metabolism is the thyroid's role, stimulating the immune system is not its function, and stimulating the heart is related to other organs/hormones.

Answer:

D. Hypothalamus
