Question

damage to the thyroid gland would interrupt which function?
lactation
sleep
fluid balance
metabolism

Explanation:

The thyroid gland produces hormones (like thyroxine) that regulate metabolism. Lactation is related to the pituitary and mammary glands, sleep is regulated by the pineal gland (melatonin) and others, and fluid balance is managed by the kidneys and hormones like ADH. So thyroid damage affects metabolism.

Answer:

D. Metabolism
