Multiple Choice Questions On Urinary System Questions
Question 1 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 2 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 3 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.
Question 4 of 5
The thin segment of loop of Henle can be distinguished from the vasa recta by all of the following EXCEPT
Correct Answer: A
Rationale: Thin segment (squamous epithelium) and vasa recta (endothelium) differ in content (urine vs. blood), wall thickness, and nuclei not epithelium type (both squamous). This corrects distinction, key for histology, contrasting with other differences.
Question 5 of 5
Structures typically seen at the border between the renal cortex and medulla are
Correct Answer: C
Rationale: Arcuate arteries/veins lie at the cortex-medulla border not interlobar (medulla), interlobular (cortex), or intralobular (misnomer). This locates junction structures, key for circulation, contrasting with other levels.
