RRB Group-D
27/09/2022 (Shift-II)
2022
✓ Answer:BHaemodialysis
Haemodialysis uses a dialyser to remove wastes and excess fluid from blood when kidney function is inadequate.

2022
✓ Answer:D95% water, 2.5% urea and 2.5% other waste products
The source uses the approximate composition of 95% water, 2.5% urea and 2.5% other dissolved substances. Actual composition varies.
883

884
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.
885
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.
886
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.
887
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.
888
Dialysis removes waste products from blood when normal kidney function is affected. Arrange the given steps in the correct sequence: a. Line to vein; b. Patient's blood passed through a tank with dialysing fluid; c. Line from artery; d. Waste products from blood pass into dialysing fluid; e. Dialysing fluid has the same osmotic pressure as blood except the wastes.
RRB Group-D
17/09/2022 (Shift-I)
2022
✓ Answer:Ac-b-e-d-a
The source sequence is c-b-e-d-a: blood enters the dialyser, is exposed across a membrane to appropriately composed dialysate, loses wastes and returns to the vein. Statement e describes the fluid rather than a separate timed step.
889
Select the correct labels a, b, c and d in the nephron diagram. Text description: a marks the blood vessel entering the renal corpuscle; b marks the capillary tuft inside it; c marks the cup surrounding that tuft; d marks the vessel draining the capillary network.
RRB Group-D
20/09/2022 (Shift-II)
2022
✓ Answer:Ba - Branch of renal artery, b - Glomerulus, c - Bowman's capsule, d - Branch of renal vein
The incoming vessel is a branch of the renal artery, the tuft is the glomerulus, the surrounding cup is Bowman's capsule and the draining vessel leads toward the renal vein.
890
Urine is composed of _____ water.
RRB Group-D
30/08/2022 (Shift-III)
2022
✓ Answer:D95%
Typical urine is approximately 95% water. The remaining portion contains urea, salts and other dissolved substances.
