The regulation of minerals such as sodium, potassium etc. in the human body is managed by which of the following glands?

  • A.Interior pancreas
  • B.Adrenal medulla
  • C.Adrenal cortex
  • D.Exterior pancreas

Answer: C

The adrenal cortex regulates mineral salts such as sodium and potassium. Its mineralocorticoids, mainly aldosterone, make the kidney retain sodium and excrete potassium. The adrenal medulla secretes adrenaline and noradrenaline for the emergency response, and the pancreas controls blood sugar through insulin and glucagon, so neither the 'interior' nor the 'exterior' pancreas is the answer.

The adrenal cortex has three zones, and aldosterone from the outer zone (zona glomerulosa) is the hormone that regulates sodium and potassium balance.
