Urinary System Mcq Questions Questions
Question 1 of 5
The process of eliminating urine from the body is called:
Correct Answer: A
Rationale: Micturition is urination not defecation (feces), filtration (kidney), or digestion (gut). This terms the voiding process, key for bladder function, contrasting with unrelated actions.
Question 2 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 3 of 5
The proximal tubules of the kidney
Correct Answer: B
Rationale: Proximal tubules have microvilli (brush border) for reabsorption not squamous (thin segment), continuous with collecting ducts (distal), or lacking basal lamina (present). This highlights reabsorption role, key for filtrate processing, contrasting with incorrect traits.
Question 4 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 5 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.
