Urinary System Test Questions And Answers Questions
Question 1 of 5
The main function of the urinary system is to:
Correct Answer: A
Rationale: The urinary system excretes waste (e.g., urea) and balances fluids/electrolytes not enzyme production (digestive), oxygen transport (respiratory), or temperature (skin). This defines its primary role, critical for homeostasis, contrasting with unrelated systems.
Question 2 of 5
The presence of glucose in urine is called:
Correct Answer: B
Rationale: Glycosuria is glucose in urine not proteinuria (protein), hematuria (blood), or pyuria (pus). This identifies diabetic marker, key for diagnosis, contrasting with other abnormalities.
Question 3 of 5
The structure that controls urine release from the bladder is the:
Correct Answer: B
Rationale: Sphincters (internal involuntary, external voluntary) control release not ureter, loop, or duct (kidney). This defines continence mechanism, key for micturition, contrasting with renal structures.
Question 4 of 5
Which of the following statements is INCORRECT
Correct Answer: B
Rationale: Efferent arterioles don't belong to the JGA (includes JG cells, macula densa, lacis cells) not incorrect are fenestrated endothelium, lacis in JGA, or podocytes on basement membrane. This corrects JGA composition, key for RAAS, contrasting with true glomerular traits.
Question 5 of 5
All the following statements about the distal convoluted tubules are CORRECT EXCEPT:
Correct Answer: A
Rationale: DCT is ~5 mm long not 14 mm; other traits (diameter, portions, microvilli, mitochondria) are correct. This corrects DCT length, key for nephron mapping, contrasting with true histological features.
