Question

Consider the following statements each with one or two blanks.
(i) The ascending limb of loop of Henle is impermeable to (1) but allows transport of (2)
(ii) (3) and (4) play a significant role in producing a concentrated urine.
(iii) A fall in glomerular blood flow/glomerular blood pressure/GFR can activate the JG cells to release (5)
Which one of the following options correctly fills the blanks in any two of the statements?

• A. $\left(1\right)$-water, $\left(2\right)$-electrolytes, $\left(5\right)$-renin
• B. $\left(3\right)$-Henle's loop, $\left(4\right)$-vasa recta, $\left(5\right)$-angiotensin
• C. $\left(1\right)$-electrolytes, $\left(2\right)$-water, $\left(3\right)$- PCT, $\left(4\right)$- DCT
• D. $\left(3\right)$-Henle's loop, $\left(4\right)$-vasa recta, $\left(5\right)$-angiotensinogen

Answer 1

The correct option is A $\left(1\right)$-water, $\left(2\right)$-electrolytes, $\left(5\right)$-renin

The ascending limb of the loop of Henle is impermeable to water but allows transport of electrolytes, while a fall in glomerular flow and pressure can activate juxtaglomerular cells to release renin.

So, the correct option is '(1)

(1)-water, (2)(2)-electrolytes, (5)(5)-renin'.
