Which hormone is released in response to low blood pressure and acts to increase the reabsorption of sodium ions in the distal convoluted tubule?
- A.Atrial Natriuretic Factor
- B.Aldosterone
- C.Antidiuretic Hormone
- D.Erythropoietin
Show correct answer & step-by-step solution
Correct answer: B — Aldosterone
Solution
- Low blood pressure triggers the renin-angiotensin-aldosterone system.
- Renin leads to the production of angiotensin II, which stimulates the adrenal cortex.
- The adrenal cortex releases aldosterone into the bloodstream.
- Aldosterone acts on the distal convoluted tubule to increase sodium reabsorption.
- Hence the answer is (B).
