Urinary System Mcq Questions Questions
Question 1 of 5
Endothelial cells of the glomerular capillaries are characterized by all of the following EXCEPT
Correct Answer: A
Rationale: Glomerular endothelium is fenestrated without diaphragms not with; proximity, lamina, and barrier role are true. This corrects endothelial structure, key for filtration, contrasting with diaphragm misconception.
Question 2 of 5
An apical brush border is associated with which of the following
Correct Answer: D
Rationale: Proximal convoluted tubules (PCT) have a brush border not collecting, loop, or DCT (few microvilli). This highlights reabsorption site, critical for filtrate processing, contrasting with other segments.
Question 3 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 4 of 5
Glands of Littre's

Rationale: Glands of Littre are mucous-secreting, prominent in male penile urethra, and present in female urethra all true. This describes urethral glands, key for lubrication, contrasting with partial traits.
Question 5 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.
