Multiple Choice Questions On Urinary System Questions
Question 1 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 2 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.
Question 3 of 5
The arteriola recta vera arise from
Correct Answer: B
Rationale: Arteriola recta vera (true) arise from arcuate arteries not interlobar, afferent, or efferent. This corrects medullary circulation, key for concentration, contrasting with efferent spuria.
Question 4 of 5
Renal filtration barrier is composed of all of the following structures EXCEPT
Correct Answer: D
Rationale: Filtration barrier includes fenestrated endothelium, basal lamina, and filtration slits none excluded. This confirms barrier components, critical for selectivity, contrasting with exclusion errors.
Question 5 of 5
Which of the following is TRUE of the kidney?
Correct Answer: C
Rationale: Proteinuria indicates filtration membrane damage not false claims: ~99% of glomerular filtrate is reabsorbed (not 50%), most nephrons are cortical (not medullary), and efferent arterioles are narrower (not wider) than afferent for pressure. This identifies a key diagnostic sign, critical for renal health assessment, contrasting with physiological errors.
