Arrange the following events occurring in Renin-Angiotensin mechanism in the correct order : Choose the correct answer from the options given below :
- A, C, E, B, D
- C, A, B, D, E
- A, D, B, E, C
- C, E, D, B, A
Answer
(4) C, E, D, B, A
Solution
A fall in GFR (C) makes JG cells release renin, which converts angiotensinogen to angiotensin I and then II (E).
Angiotensin II causes vasoconstriction and aldosterone release (D).
Aldosterone increases Na+ and water reabsorption from distal tubule parts (B), raising blood pressure and GFR (A).
Order: C, E, D, B, A.
