Urinary System Mcq Questions Questions
Question 1 of 5
All the following hormones are secreted by the kidney EXCEPT
Correct Answer: A
Rationale: Rennin' (digestive enzyme) isn't renal renin, medullipin, and EPO are. This corrects terminology, critical for renal endocrinology, contrasting with true hormones.
Question 2 of 5
Which of the following would be a consequence of renal failure?
Correct Answer: D
Rationale: Renal failure reduces erythropoietin (RBC synthesis), pH regulation (H+ excretion), and waste clearance (urea increase) all apply. Each consequence reflects lost kidney functions: EPO production, acid-base balance, and filtration. Ignoring any (RBC, pH, waste) underestimates failure's impact, making 'all' correct. This comprehensively links failure to systemic effects, key for clinical understanding, contrasting with partial outcomes.
Question 3 of 5
The ureteric bud in contact with the metanephric cap gives:
Correct Answer: D
Rationale: Ureteric bud forms collecting tubules, minor/major calyces all urinary collecting structures via branching with the metanephric cap. 'All' reflects its full role, critical for kidney drainage, contrasting with partial calyceal focus.
Question 4 of 5
The urinary bladder is:
Correct Answer: A
Rationale: Bladder (vesicourethral canal) is endodermal not mesodermal (trigone), ectodermal, all, or mixed; cloacal endoderm forms it. This defines germ layer, key for embryology, contrasting with mesodermal trigone.
Question 5 of 5
Which of the following is NOT a function of the urinary system?
Correct Answer: D
Rationale: The urinary system doesn't preserve water-sugar balance regulates water, electrolytes, not glucose (e.g., PCT reabsorbs all glucose). Blood pressure maintenance via renin true. Metabolic waste excretion (urea) core function. Acid-base balance via H /HCO₃⻠correct. Water-sugar misaligns glucose isn't urinary-regulated distinguishing it, key to urinary specificity, unlike established roles.
