Arrange the following events occuring in Renin-Angiotensin mechanism in the correct order:
A. Increase in blood pressure and Glomerular filtration rate
B. Reabsorption of Na and water from distal parts of tubule due to Aldosterone
C. Fall in Glomerular filtration rate
D. Vasoconstriction by Angiotensin II and release of Aldosterone.
E. Renin converts Angiotensinogen into Angiotensin I, followed by Angiotensin II.
Choose the correct answer from the options given below:
- A
A, C, E, B, D
- B
C, A, B, D, E
- C
A, D, B, E, C
- D
C, E, D, B, A
The juxtaglomerular apparatus (JGA) responds to a fall in glomerular blood flow / GFR (C) by releasing renin, which converts angiotensinogen first to angiotensin I and then to angiotensin II (E).
Angiotensin II causes vasoconstriction and stimulates the adrenal cortex to release aldosterone (D).
Aldosterone promotes reabsorption of Na and water from the distal parts of the tubule (B).
This raises blood pressure and restores GFR (A).
Correct order: C → E → D → B → A.
