Which of the following compounds most commonly forms kidney stones?
RRB NTPC (Stage-I)
02/04/2016 (Shift-II)
2016
✓ Answer:ACalcium oxalate
Calcium oxalate is the most common constituent of kidney stones.
42
Which letter represents Bowman's capsule in the nephron diagram? Text description: a labels the cup-shaped beginning; b labels the tube leaving the cup; c labels the bottom of the U-shaped bend; d labels the upper end of the returning limb.
RRB Group-D
12/09/2022 (Shift-I)
2022
✓ Answer:ARegion a
Bowman's capsule is the cup-shaped structure at the beginning of the nephron, shown as region a.
43
Bowman's capsule encloses _____.
RRB Group-D
06/10/2022 (Shift-III)
2022
✓ Answer:AThe glomerulus
Bowman's capsule surrounds the glomerular capillary tuft and collects the filtrate produced from blood.
44
Which of the following statements is INCORRECT?
RRB Group-D
12/09/2022 (Shift-II)
2022
✓ Answer:BEach kidney has large numbers of filtration units called neurons packed close together.
The kidney's filtration units are nephrons, not neurons. Neurons are nerve cells.
45
Is there any advantage to the nephron having a long tubular structure?
RRB Group-D
13/09/2022 (Shift-II)
2022
✓ Answer:CYes, the long tube gives time and space for reabsorption of excess water from the initial filtrate.
The long renal tubule provides time and surface area for selective reabsorption of water and useful solutes, as well as secretion.
46
Kidney failure is treated periodically on a kidney machine. The process is known as _____.
RRB NTPC (Stage-I)
16/01/2021 (Shift-II)
2021
✓ Answer:AHaemodialysis
Haemodialysis passes blood through an external dialyser to remove wastes and excess fluid.
47
A dialyser, a machine used to clean a patient's blood, is also known as an artificial:
RRB NTPC (Stage-I)
08/04/2021 (Shift-I)
2021
✓ Answer:CKidney
A dialyser is called an artificial kidney because it performs part of the kidneys' waste-removal function.
48
Which of the following is not a part of the human excretory system?
RRB NTPC (Stage-I)
08/03/2021 (Shift-II)
2021
✓ Answer:DBronchiole
Bronchioles are small respiratory airways. The collecting duct, glomerulus and Bowman's capsule are kidney structures.
49
In the treatment of which condition is dialysis involved?
RRB NTPC (Stage-I)
31/03/2016 (Shift-II)
2016
✓ Answer:CRenal failure
Dialysis replaces some kidney functions in renal failure by removing wastes and excess fluid from the blood.
50
The process of dialysis is related to the:
RRB Group-D
24/10/2018 (Shift-I)
2018
✓ Answer:DKidney
Dialysis performs part of the kidneys' function when they cannot adequately remove wastes and excess fluid.
