Remembering +4 | -1

The osmolarity of the glomerular filtrate in distal convoluted tubule of nephron is around

View answer and explanation

Correct option: B

200\mathrm{ }mOsmol\mathrm{ }{L^{ - 1}}

Option B is correct because the osmolarity of the glomerular filtrate in the distal convoluted tubule (DCT) is around 200 mOsmol/L after dilution in the ascending limb of the loop of Henle.

74 Easy

74 of 105

Understanding +4 | -1

What happens in micturition?

View answer and explanation

Correct option: D

All of the above

Option D (All of the above) is correct because micturition involves contraction of bladder muscles, relaxation of the urethral sphincter, and release of urine.

75 Easy

75 of 105

Analyzing +4 | -1

Assertion (A): Dialytic fluid/solution is iso-osmotic to blood plasma
Reason (R): The fluid used during dialysis procedure contains urea, glucose and ions.

View answer and explanation

Correct option: D

If A is false, but R is true

Option D is correct. Dialytic fluid is iso-osmotic to blood plasma is false, and the fluid used during dialysis contains urea, glucose, and ions is true.

76 Easy

76 of 105

Understanding +4 | -1

Choose the mismatched part of nephron with their function

View answer and explanation

Correct option: C

DCT – Reabsorption of glucose

Option C is correct because the DCT primarily reabsorbs sodium, chloride, and water (under the influence of ADH), not glucose. Glucose reabsorption occurs in the PCT.

77 Easy

77 of 105

Understanding +4 | -1

During urine formation in nephrons, renal filtrate in Henle’s loop is without

View answer and explanation

Correct option: B

Glucose

Option B is correct because glucose is normally completely reabsorbed in the proximal convoluted tubule (PCT) and is therefore absent in the filtrate within the loop of Henle.

78 Easy

78 of 105

Remembering +4 | -1

Most of the secretory product of liver ultimately pass out along with

View answer and explanation

Correct option: B

Digestive wastes

Option B (Digestive wastes) is correct because the liver's secretory products, including bile, are released into the digestive system and ultimately excreted with feces.

Correct option: D

Podocytes - Create minute spaces (slit pore) for the filtration of blood into the lumen of Bowmann's capsule

Option D (Podocytes - Create minute spaces (slit pore) for the filtration of blood into the lumen of Bowmann's capsule) is correct because podocytes are specialized cells in Bowman's capsule that have filtration slits allowing for the passage of small molecules into the filtrate.

82 Easy

82 of 105

Understanding +4 | -1

In micturition,

View answer and explanation

Correct option: A

Assertion: Aldosterone leads to the increase in blood pressure.
Reason: Aldosterone causes reabsorption of sodium ion and water from distal part of tubules

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

The correct answer is A (If both the assertion and the reason are true and the reason is a correct explanation of the assertion) because aldosterone does increase blood pressure by promoting sodium and water reabsorption.

84 of 105

Understanding +4 | -1

In mammals, which blood vessels would normally carry largest amount of urea

View answer and explanation

Correct option: C

hepatic vein

Option C (hepatic vein) is correct because the liver converts ammonia to urea, which is then released into the hepatic vein.

85 of 105

Remembering +4 | -1

Human kidneys can produce urine nearly

View answer and explanation

86 of 105

Understanding +4 | -1

Select the incorrectly matched

View answer and explanation

Correct option: B

Henle’s loop – formation of concentrated urine

Option A (proximal convoluted tubule – ionic balance) is incorrect because while the PCT does contribute to ionic balance, its primary role is reabsorption of glucose, amino acids, and water, not primarily ionic balance. The DCT plays a more significant role in ionic balance.

87 Easy

87 of 105

Understanding +4 | -1

Normally, which is absent in glomerular filtrate is

View answer and explanation

Correct option: A

albumin

Option A (albumin) is correct because albumin is a large protein that is normally not filtered through the glomerulus due to its size.

Inner to the hilum of the kidney, there is a broad funnel-shaped space called

View answer and explanation

Correct option: A

Renal pelvis

Option A (Renal pelvis) is correct because the renal pelvis is the funnel-shaped space inner to the hilum of the kidney.

Option C is correct because uremia refers to the accumulation of urea and other nitrogenous waste products in the blood.

90 Easy

90 of 105

Understanding +4 | -1

Increase in blood pressure is caused by
