✓ Answer:DKidney
Dialysis is used for severe impairment of kidney function to remove wastes and excess fluid.
52
Ultrafiltration is related to:
RRB Group-D

2018
✓ Answer:CExcretion
Glomerular ultrafiltration in the kidneys is the first stage of urine formation and is part of excretion.
53
We can control the stimulation of urination:

✓ Answer:AWhen the muscular bladder is under nerve control.
The source selects A. Urination is regulated by nervous control of the bladder and urethral sphincters; voluntary control particularly involves the external urethral sphincter.
54
Find the odd one out.
RRB Group-D
12/11/2018 (Shift-III)
2018
✓ Answer:ANissl's granules
Nissl's granules are found in neurons. The other three structures are parts of a nephron.
55
Which of these organs is not related to the excretory system?
RRB Group-D
15/11/2018 (Shift-II)
2018
✓ Answer:ACoronary artery
The source selects the coronary artery, which supplies the heart. The other vessels serve organs involved in waste handling. All four options are blood vessels, so the question uses 'excretory system' broadly.
56
_____ is present in the lining of the renal tubule.
RRB Group-D
27/11/2018 (Shift-I)
2018
✓ Answer:CCuboidal epithelium
Much of the renal tubule is lined by simple cuboidal epithelium, suited to absorption and secretion. Thin loop segments have squamous epithelium.
57
In humans, which of the following is the function of the nephrons?
RRB Group-D
03/12/2018 (Shift-III)
2018
✓ Answer:BExcretion
Nephrons form urine, removing metabolic wastes and helping regulate water, electrolyte and acid-base balance.
58
_____ is a 20 cm long tube that carries urine from the bladder.
RRB Group-D
16/10/2018 (Shift-I)
2018
✓ Answer:BUrethra
The urethra carries urine from the bladder to the outside. The approximately 20 cm length refers to the male urethra; the female urethra is much shorter.
59
Which human body organ is involved in the purification of blood?
RRB NTPC (Stage-I)
18/04/2016 (Shift-II)
2016
✓ Answer:CKidney
The kidneys filter blood and remove metabolic wastes through urine formation.
60
Nephrology is associated with _____.
RRB NTPC (Stage-I)
06/04/2016 (Shift-I)
2016
✓ Answer:CKidney
Nephrology is the branch of medicine concerned with the kidneys and their disorders.
