14 of 269

Remembering +4 | -1

Hemodialysis is most commonly used for treating

View answer and explanation

Correct option: B

Uremia

Option B is correct because hemodialysis is a common treatment for uremia, helping to remove waste products from the blood when the kidneys are not functioning properly.

15 Medium

15 of 269

Remembering +4 | -1

Understanding +4 | -1

NaCl is returned to interstitium by

View answer and explanation

Correct option: C

Ascending limb of vasa recta

Option C (Ascending limb of vasa recta) is correct because the ascending limb of the vasa recta carries blood away from the medulla, picking up NaCl that was reabsorbed from the ascending limb of the Loop of Henle.

18 Easy

Remembering +4 | -1

Uric acid is the chief nitrogenous excretory component of

View answer and explanation

Correct option: C

Cockroach

Option C (Cockroach) is correct because cockroaches, being insects, primarily excrete uric acid as their main nitrogenous waste product.

19 of 269

Understanding +4 | -1

Which of the following pairs is wrong?

View answer and explanation

Correct option: B

ammonotelic - insects

Option B (ammonotelic - insects) is wrong because insects are primarily uricotelic, excreting uric acid to conserve water, not ammonia.

20 Medium

Human sweat is a watery fluid containing

View answer and explanation

Correct option: D

All of these

Option D is correct because human sweat contains NaCl, urea, and lactic acid.

Understanding +4 | -1

An organism which don’t have loop of Henle will excrete

View answer and explanation

Correct option: B

Dilute urine

Option B (Dilute urine) is correct because the loop of Henle is responsible for concentrating urine.

Identify the true statements and choose the correct option accordingly
I. Blood vessel leading to the glomerulus is called efferent arteriole
II. Vasa-recta, peritubular capillaries and glomerulus, all have blood
III. Cortical nephrons have highly reduced vasa-recta
IV. Vasa-recta runs parallel to the Henle’s loop in the juaxta-medullary nephron

View answer and explanation

Correct option: D

II, III and IV

Option D (II, III and IV) is correct because vasa recta, peritubular capillaries, and glomerulus all contain blood, cortical nephrons have reduced vasa recta, and vasa recta runs parallel to Henle's loop in juxtamedullary nephrons.

23 Easy

In a person, the nephrons receive around

1200\, \mathrm{~mL}

of blood per minute, whereas the glomerular filtration rate is

125\, \mathrm{~mL} / \mathrm{min}

. What would be the renal plasma flow (

RPF

) and filtration fraction (

FF

) in such a person?

View answer and explanation

Correct option: D

{RPF}=660 \,\mathrm{~mL}, {FF} \simeq 18

\,

per cent

Option D (

{RPF}=660 \,\mathrm{~mL}, {FF} \simeq 18

\,\mathrm{per\,cent}

) is correct because renal plasma flow is calculated by assuming hematocrit is about 45%, and filtration fraction is GFR/RPF.

25 Medium

25 of 269

Remembering +4 | -1

Urea synthesis occurs in

View answer and explanation

Correct option: B

Liver

Option B (Liver) is correct because the urea cycle, which synthesizes urea, occurs in the liver.

Understanding +4 | -1

RAAS

View answer and explanation

Correct option: D

Both (a) and (b)

The correct answer is D (Both (a) and (b)) because RAAS is triggered by renin release from JGA cells and is responsible for regulating kidney function.

27 of 269

Understanding +4 | -1

Which of the following is the ultimate method of the correction of renal failure?

View answer and explanation

Correct option: A

Kidney transplant

Option A (Kidney transplant) is correct because a kidney transplant is the ultimate method for correcting renal failure, as it replaces the non-functioning kidney with a healthy one.

28 Easy

Assertion: Most of the secretion of liver is pass out along with faecal matter
Reason: Bile juice is secreted in digestive tract.

View answer and explanation

Correct option: A

If both the assertion and the reason are true and the reason is a correct explanation of the assertion

Option A (If both the assertion and the reason are true and the reason is a correct explanation of the assertion) is correct because the liver secretes bile into the digestive tract, and much of what the liver processes is eventually eliminated with feces.

29 Medium

29 of 269

Remembering +4 | -1

Urine is concentrated in which part of nephron

View answer and explanation

Correct option: A

Option A is correct because urine is concentrated in the collecting tubule (CT) due to the countercurrent mechanism.

Select the odd one w.r.t regulation by Renin-angiotensin system

View answer and explanation

Correct option: B

ANF

The correct answer is B (ANF) because ANF acts antagonistically to the Renin-Angiotensin system, decreasing blood pressure, while the others are components of the RAAS system which increases blood pressure.
