Questions About The Urinary System Questions
Question 1 of 5
Renal lobule includes
Correct Answer: C
Rationale: Renal lobule is a medullary ray plus draining nephrons not pyramid (lobe), cortex, or artery-based. This defines cortical unit, key for histology, contrasting with lobe or vascular definitions.
Question 2 of 5
The non-glomerular blood circulation of the kidney includes all of the following EXCEPT
Correct Answer: C
Rationale: Peritubular capillaries are glomerular (efferent) not non-glomerular like capsular, terminal, or recta vera. This corrects circulation type, critical for reabsorption, contrasting with post-glomerular inclusion.
Question 3 of 5
Structure typically seen at the border between the renal cortex and medulla include:
Correct Answer: D
Rationale: Arcuate arteries/veins mark cortex-medulla border not vasa recta (medulla), stellate (cortex), peritubular (cortex), or interlobular (cortex). This repeats Q32, key for circulation, contrasting with other locations.
Question 4 of 5
The lateral end of the pronephric tubules opens in:
Correct Answer: D
Rationale: Lateral ends of pronephric tubules connect to the intraembryonic coelomic cavity not amniotic, yolk sac, extraembryonic coelom, or duct (medial). This reflects their nephrotome origin, key for early filtration, contrasting with medial drainage or external spaces.
Question 5 of 5
The polycystic kidney is due to failure of communication between:
Correct Answer: C
Rationale: Polycystic kidney results from failed DCT-collecting tubule fusion not PCT-DCT, Bowman's-PCT, or calyceal issues; cysts form at this junction. This pinpoints defect, critical for pathology, contrasting with other nephron stages.
