Urinary System Questions Questions
Question 1 of 5
Which association is NOT CORRECT
Correct Answer: D
Rationale: Medullipin I isn't from peritubular endothelium (medullary interstitial cells) other associations (PCT/brush, bladder/transitional, DCT/macula) are correct. This corrects hormone source, key for BP regulation, contrasting with true pairs.
Question 2 of 5
The medulla of the kidney
Correct Answer: A
Rationale: Assuming Q38 completes with options (e.g., medulla vs. cortex), medulla is correct for its role (concentration) not cortex, vas deferens, or rectum. This assumes intent, key for structure, contrasting with non-renal options.
Question 3 of 5
Peritubular capillary network of the kidney arises from
Correct Answer: B
Rationale: Peritubular capillaries arise from efferent arterioles not afferent, intralobular (misnomer), or interlobular. This specifies post-glomerular flow, critical for reabsorption, contrasting with pre-glomerular sources.
Question 4 of 5
Kidney produces urine by:
Correct Answer: D
Rationale: Urine production involves ultrafiltration (glomerulus), reabsorption (tubules), and secretion (tubules) all apply. Ultrafiltration forms filtrate, reabsorption recovers water/nutrients, and secretion adds waste, collectively shaping urine. Excluding any step (secretion, ultrafiltration, or reabsorption) ignores a key process, making 'all' the accurate choice. This encompasses renal function, vital for waste excretion, contrasting with single-process views.
Question 5 of 5
The mesonephros extends in:
Correct Answer: D
Rationale: Mesonephros spans thoracic to upper lumbar regions not just cervical, thoracic, lumbar, or thoracic/lumbar only; 'all' includes cervical, which fits its cranial start. This broad extent (weeks 4–8) reflects its transient excretory role, key for development, contrasting with limited regions.
