Multiple Choice Questions On Urinary System Questions
Question 1 of 5
Blood is filtered in the:
Correct Answer: C
Rationale: The glomerulus filters blood into Bowman's capsule not loop of Henle (reabsorption), ureter (transport), or collecting duct (concentration). This pinpoints filtration site, critical for GFR, contrasting with later nephron segments.
Question 2 of 5
Dialysis is used to:
Correct Answer: B
Rationale: Dialysis filters blood in renal failure not gallstones (surgery), BP (meds), or UTIs (antibiotics). This explains its purpose, critical for ESRD, contrasting with unrelated treatments.
Question 3 of 5
The main function of the collecting ducts in the nephron is to:
Correct Answer: B
Rationale: Collecting ducts transport concentrated urine to pelvis not filter (glomerulus), reabsorb glucose (PCT), or digest (gut). This specifies final conduit, critical for urine delivery, contrasting with earlier roles.
Question 4 of 5
The cells of the visceral layer of renal corpuscle are called:
Correct Answer: B
Rationale: Podocytes form the visceral layer of the renal corpuscle not mesangial (support), extra-glomerular (lacis), or JG cells (arterioles). This identifies filtration cells, critical for GFR, contrasting with support/control cells.
Question 5 of 5
The glomerular basement membrane
Correct Answer: D
Rationale: GBM fuses capillary/podocyte laminae, is ~320-340 nm thick, and is renewed by mesangial cells all true. This fully describes GBM, critical for filtration barrier, contrasting with partial features.
