Questions On The Urinary System Questions
Question 1 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 2 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 3 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.
Question 4 of 5
The mesonephric tubules in male gives:
Correct Answer: A
Rationale: In males, mesonephric tubules form vasa efferentia (testis to epididymis) not epididymis duct, vas deferens, ejaculatory duct (from mesonephric duct), or all. This specifies tubule fate, key for reproductive anatomy, contrasting with duct derivatives.
Question 5 of 5
The caudal somites migrate to give the following except:
Correct Answer: D
Rationale: Caudal somites form genital tubercle, swellings, external sphincter, and abdominal wall not internal anal sphincter (splanchnic mesoderm). This excludes visceral muscle, key for somitic roles, contrasting with included derivatives.
