Multiple Choice Questions On Urinary System Questions
Question 1 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 2 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 3 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.
Question 4 of 5
The vesico-urethral canal gives rise to:
Correct Answer: B
Rationale: Vesicourethral canal forms most of the bladder not whole (trigone from mesonephric ducts), prostatic urethra (partly sinus), female urethra (sinus), or all; 'most' fits. This specifies bladder origin, critical for development, contrasting with full scope.
Question 5 of 5
Excretion is the removal of __________ from the body.
Correct Answer: C
Rationale: Excretion removes metabolic waste e.g., urea, COâ‚‚ from cellular processes (kidneys, lungs). Undigested food waste is defecation not excretion in this context. Used hormones are degraded not primarily excreted whole. Pathogens are fought by immunity not routinely excreted. Metabolic waste's removal distinguishes it, critical for homeostasis, unlike fecal, hormonal, or immune processes.
