Questions On The Urinary System Questions
Question 1 of 5
All of the following are TRUE about the juxta-glomerular cells EXCEPT
Correct Answer: B
Rationale: JG cells are in afferent arterioles not DCT (macula densa); other traits (smooth muscle, innervation, RER/Golgi) are true. This corrects location, key for renin secretion, contrasting with DCT misplacement.
Question 2 of 5
Cells lining the renal collecting ducts and tubules include
Correct Answer: D
Rationale: Collecting ducts have principal (water) and intercalated (acid-base) cells not lacis (JGA). This specifies cell types, critical for concentration, contrasting with JGA inclusion.
Question 3 of 5
The arteriolar recta spuria arise from
Correct Answer: D
Rationale: Arteriola recta spuria (false) arise from efferent arterioles not interlobar, interlobular, or afferent. This specifies medullary supply, critical for countercurrent, contrasting with other origins.
Question 4 of 5
Ducts of Bellini
Correct Answer: D
Rationale: Ducts of Bellini are large (200-300 μm), columnar-lined, and empty at area cribrosa all true. This fully describes papillary ducts, key for urine delivery, contrasting with partial features.
Question 5 of 5
Filtrate in the distal convoluted tubule:
Correct Answer: A
Rationale: Filtrate in the distal convoluted tubule (DCT) has just exited the loop of Henle not pre-loop (PCT), pre-glomerulus (blood), or pre-PCT (glomerulus). The loop concentrates filtrate before DCT fine-tunes it, placing it post-loop in the nephron sequence. This clarifies filtrate progression, key for nephron function, contrasting with earlier stages.
