MatchList IwithList II
| List I (Hormone) | List II (Role in regulating kidney function) |
|---|---|
| (A). Renin | (I). Increases blood pressure by vasoconstriction in kidney |
| (B). Angiotensin II | (II). Stimulates reabsorption of water in DCT and CD |
| (C). ANP | (III). Stimulates formation of Angiotensin I |
| (D). ADH | (IV). Stimulates natriuresis and diuresis |
Choose thecorrectanswer from the options given below:
Options:
Answer:
Solution:
Renin is secreted by the juxtaglomerular (JG) cells and converts angiotensinogen in the blood to Angiotensin I. Thus, (A) matches (III).
Angiotensin II is a potent vasoconstrictor that increases blood pressure and glomerular filtration rate (GFR). Thus, (B) matches (I).
Atrial Natriuretic Peptide (ANP) is released by the atria of the heart in response to high blood pressure. It causes vasodilation and promotes the excretion of sodium (natriuresis) and water (diuresis) in the urine. Thus, (C) matches (IV).
Antidiuretic Hormone (ADH) or vasopressin facilitates the reabsorption of water from the distal convoluted tubule (DCT) and collecting duct (CD), preventing diuresis. Thus, (D) matches (II).
The correct matching is (A) - (III), (B) - (I), (C) - (IV), (D) - (II).
Answer: (A) - (III), (B) - (I), (C) - (IV), (D) - (II)
