Multiple Choice Questions On Urinary System Questions
Question 1 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 2 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 3 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 4 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.
Question 5 of 5
The mesonephric tubules in female gives:
Correct Answer: D
Rationale: In females, mesonephric tubules form epoophoron, paroophoron, and their ducts all vestigial remnants. 'All' includes these Gartner's duct precursors, critical for understanding female rudiments, contrasting with partial selections.
