Questions About The Urinary System Questions
Question 1 of 5
The distal convoluted tubules have
Correct Answer: D
Rationale: DCT has faint acidophilic cytoplasm, basal infoldings, and large mitochondria all true. This describes DCT histology, critical for ion transport, contrasting with partial traits.
Question 2 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 3 of 5
The function of collecting tubules
Correct Answer: B
Rationale: Collecting tubules reabsorb ~9% water (ADH-dependent) not K+ (DCT), 80% (PCT), or Na+ (earlier). This specifies water role, key for concentration, contrasting with earlier reabsorption.
Question 4 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 5 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.
