Urinary System Mcq Questions Questions
Question 1 of 5
The structure that connects a kidney to the urinary bladder is the
Correct Answer: A
Rationale: Ureter transports urine from kidney to bladder not urethra (bladder out), pelvis (inside), or duct (nephron). This identifies urine conduit, key for flow, contrasting with other structures.
Question 2 of 5
Production of less than 50 mL/day of urine is called ________.
Correct Answer: D
Rationale: Anuria is <50 mL/day not normal (~1-2 L), polyuria (excess), or oliguria (100-400 mL). This defines severe reduction, key for renal failure, contrasting with higher outputs.
Question 3 of 5
What are the names of the capillaries following the efferent arteriole?
Correct Answer: C
Rationale: Peritubular (cortex) and vasa recta (medulla) follow efferent arteriole not arcuate, interlobar, or medullary alone. This specifies post-glomerular flow, key for reabsorption, contrasting with other vessels.
Question 4 of 5
Progesterone can bind to receptors for which hormone that, when released, activates water retention?
Correct Answer: A
Rationale: Progesterone mimics aldosterone (Na+/water retention) not ADH (water), PTH (Ca2+), or ANH (natriuretic). This specifies cross-reactivity, critical for fluid balance, contrasting with direct water hormones.
Question 5 of 5
Which is found in the highest concentration in the urine?
Correct Answer: B
Rationale: Urea is the most concentrated waste in urine not uric acid, glucose (reabsorbed), or creatinine (less). This identifies excretory priority, critical for nitrogen, contrasting with reabsorbed solutes.
