Urinary System Test Questions And Answers Questions
Question 1 of 5
Which muscle metabolism waste product is eliminated by the kidneys?
Correct Answer: D
Rationale: Creatinine, from muscle creatine breakdown, is excreted by kidneys, unlike urea (protein), uric acid (purines), or creatine (precursor). This identifies muscle-specific waste, key for renal clearance, contrasting with other metabolites.
Question 2 of 5
The kidneys are located in the space.
Correct Answer: D
Rationale: Kidneys are retroperitoneal (behind peritoneum), not pelvic, peritoneal, or abdominal (general). This specifies anatomical position, key for surgical access, contrasting with intraperitoneal organs.
Question 3 of 5
Uric acid results from metabolism.

Correct Answer: C
Rationale: Bladder mucosa is transitional epithelium, adapting to stretch, not smooth muscle (wall), squamous, or columnar (glands). This specifies bladder lining, key for expansion, contrasting with other epithelia.
Question 5 of 5
The countercurrent multiplier mechanism occurs at the
Correct Answer: B
Rationale: Countercurrent multiplier in the loop of Henle concentrates urine, not PCT, DCT, or collecting ducts (ADH effect). This locates concentration mechanism, key for osmolarity, contrasting with other segments.
