2023 Manipur Excretory Products and their EliminationRenin-Angiotensin-Aldosterone mechanism Medium Question 13 of 60 in Excretory Products and their Elimination

Arrange the events of Renin - Angiotensin mechanism in correct sequence. (A) Activation of JG cells and release of renin. (B) Angiotensin II activates release of aldosterone. (C) Fall in glomerular blood pressure. (D) Reabsorption of $Na^+$ and water from distal convoluted tubule. (E) Angiotensinogen is converted to Angiotensin I and then to Angiotensin II.

A (C), (A), (E), (B), (D)
B (A), (D), (E), (C), (B)
C (A), (D), (C), (B), (E)
D (B), (A), (E), (D), (C)

The answer is A.

Solution

Correct sequence: Fall in glomerular blood pressure (C) → Activation of JG cells and release of renin (A) → Angiotensinogen is converted to Angiotensin I and then to Angiotensin II (E) → Angiotensin II activates release of aldosterone (B) → Reabsorption of $Na^+$ and water from the distal convoluted tubule (D). Order: C, A, E, B, D.
