Questions About The Urinary System Questions
Question 1 of 5
Which of the following statements concerning the kidneys is false?
Correct Answer: D
Rationale: Kidneys are retroperitoneal, have 8-15 pyramids, distinct cortex/medulla, but span T12-L3 not L3-L5. This corrects positioning, vital for anatomy, contrasting with true traits.
Question 2 of 5
Which part of the urinary system is not completely retroperitoneal?
Correct Answer: C
Rationale: Bladder is partially peritoneal (superior covered) not kidneys, ureters (retroperitoneal), or nephrons (within kidney). This corrects position, vital for anatomy, contrasting with full retroperitoneal parts.
Question 3 of 5
Most absorption and secretion occurs in this part of the nephron.
Correct Answer: A
Rationale: PCT handles ~65-70% reabsorption and secretion not loop, DCT, or collecting (fine-tuning). This specifies primary site, key for filtrate processing, contrasting with later segments.
Question 4 of 5
Which hormone does the kidney produce that stimulates red blood cell production?
Correct Answer: C
Rationale: Erythropoietin (EPO) from kidneys boosts RBCs not thrombopoietin, vitamin D, or renin. This specifies hematopoietic role, key for anemia, contrasting with other hormones.
Question 5 of 5
The micturition reflex center is located in the _____.
Correct Answer: D
Rationale: Micturition reflex is in sacral plexus (S2-S4) not pons, midbrain, or lumbar. This locates control, key for voiding, contrasting with higher centers.
