1. NEET 2026HardUrine formation
   Q1

   Match List I with List II:
   
   List-I:
   
   A. Cortisol,
   
   B. Aldosterone,
   
   C. Cholecystokinin,
   
   D. Progesterone
   
   List-II:
   
   I. Stimulates the formation of alveoli in mammary glands,
   
   II. Produces anti-inflammatory reactions,
   
   III. Stimulates reabsorption of Na⁺ and water from renal tubule,
   
   IV. Stimulates secretion of pancreatic
   
   enzymes and bile juice
   
   Choose the correct answer from the options given below:

   • AA-III, B-II, C-IV, D-I
   • BA-IV, B-II, C-I, D-III
   • CA-II, B-III, C-IV, D-I
   • DA-II, B-III, C-I, D-IV

   Show answer & solution

   Correct answer: (C)

   Cortisol -- anti-inflammatory (II); Aldosterone -- Na⁺/water reabsorption (III); CCK -- pancreatic enzymes/bile (IV); Progesterone -- alveoli formation (I). So A-II, B-III, C-IV, D-I.
2. NEET 2026MediumRegulation of kidney function
   Q2

   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:

   • AA, C, E, B, D
   • BC, A, B, D, E
   • CA, D, B, E, C
   • DC, E, D, B, A

   Show answer & solution

   Correct answer: (D)

   Fall in GFR (C) → Renin release → Angiotensin II (E) → Vasoconstriction & Aldosterone (D) → Na⁺/water reabsorption (B) → increase BP and GFR (A). So C, E, D, B, A.
3. NEET 2025MediumHuman excretory system and kidney structure
   Q3

   In frog, the Renal portal system is a special venous connection that acts to link:

   • AKidney and intestine
   • BKidney and lower part of body
   • CLiver and intestine
   • DLiver and kidney

   Show answer & solution

   Correct answer: (B)

   In frogs, there are specialized venous connections that serve specific functions. One such connection links the liver and intestine, known as the hepatic portal system. Another connects the kidney to the lower parts of the body; this is referred to as the renal portal system. The renal portal system specifically involves the transfer of blood from the lower regions of the body to the kidneys.
