Year 2024 Total
Questions 2 2

Arrange the following events occurring 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:

Solution & Explanation

Related Formula

Fall in GFR arrow Renin release arrow Angiotensinogen arrow Angiotensin I arrow Angiotensin II arrow Aldosterone arrow Increased GFR

Core Logic

The step-by-step sequence of the RAAS mechanism is:

  • Fall in glomerular filtration rate (GFR) / blood flow (C)
  • JG cells release Renin, converting Angiotensinogen to Angiotensin I and then to Angiotensin II (E)
  • Angiotensin II causes vasoconstriction and stimulates adrenal cortex to release Aldosterone (D)
  • Aldosterone causes reabsorption of Na^+ and H₂O from DCT (B)
  • Increase in blood pressure and GFR back to normal (A)
Step 1: Sequence Order

The correct order is C arrow E arrow D arrow B arrow A.

Pattern Recognition

Sees: "Renin-Angiotensin mechanism order". Shortcut: Starts with Fall in GFR (C) and ends with Increase in BP/GFR (A).

Q175 neet_2024_05_may_morning Juxtaglomerular Apparatus (JGA) Composition
The JGA (Juxta Glomerular Apparatus) is a special sensitive region formed by cellular modifications in ____ related to the same nephron.
  • A. Distal convoluted tubule and afferent renal arteriole
  • B. Proximal convoluted tubule and afferent renal arteriole
  • C. Distal convoluted tubule and efferent renal arteriole
  • D. Proximal convoluted tubule and efferent renal arteriole

Solution

Related Formula
JGA Composition = Distal Convoluted Tubule (Macula Densa) + Afferent Renal Arteriole (JG Cells)
Core Logic

Juxtaglomerular Apparatus (JGA) is formed by cellular modifications in the distal convoluted tubule (DCT) and the afferent renal arteriole at the point of their physical contact.

Step 1: Conclusion

The correct combination is DCT and afferent renal arteriole.

Pattern Recognition

Sees: "JGA cellular modifications". Shortcut: Distal convoluted tubule + Afferent renal arteriole.
