Question

Zona glomerulosa or glomerular area of adrenal cortex is involved in

• A. Water and electrolyte balance
• B. Carbohydrate metabolism
• C. Steroid and hormone secretion
• D. Blood pressure

Answer 1

Answer: (A)

Water and electrolyte balance

Zona glomerulosa is the superficial layer of adrenal cortex (outer region of kidney) which secretes aldosterone. It is a mineralocorticoid and maintains water and electrolyte balance of body as it stimulates absorption of water and sodium and promotes excretion of potassium. It also participates in RAAS (Rennin-angiotensin-aldosterone-system) mechanism to regulate blood pressure an fluid balance in the body.

So, the correct answer is 'Water and electrolyte balance'.
