Urinary System Mcq Questions Questions
Question 1 of 5
The renal corpuscle does not contain
Correct Answer: C
Rationale: The renal corpuscle (glomerulus + Bowman's capsule) includes mesangial cells (support), filtration slits (podocytes), and glomerulus (capillaries), but macula densa is in the distal tubule, part of the juxtaglomerular apparatus not the corpuscle. This distinguishes structural components, key for filtration anatomy, contrasting with JGA elements.
Question 2 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 3 of 5
Facet cells
Correct Answer: D
Rationale: Facet cells (surface transitional epithelium) are cuboidal/binucleated and form an osmotic barrier all true. This describes bladder lining, critical for protection, contrasting with partial traits.
Question 4 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 5 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.
