Questions On The Urinary System Questions
Question 1 of 5
With respect to glomerular filtration:
Correct Answer: A
Rationale: Glomerular filtration is passive ultrafiltration not unaffected by RBF (affects pressure) or 137 L/min (180 L/day). This corrects filtration mechanics, critical for GFR, contrasting with rate or flow errors.
Question 2 of 5
The micturition reflex center is located in the:
Correct Answer: C
Rationale: Micturition reflex centers in sacral cord (S2-S4) not kidney, cerebrum, bladder, or hypothalamus. This locates reflex control, key for voiding, contrasting with higher/organ sites.
Question 3 of 5
Diabetes insipidus or diabetes mellitus would most likely be indicated by ________.
Correct Answer: B
Rationale: Polyuria (excess urine) marks diabetes insipidus (ADH lack) and mellitus (glucose diuresis) not anuria (none), oliguria (low), or none. This links conditions to output, key for diagnosis, contrasting with reduced flow.
Question 4 of 5
The right kidney is slightly lower because ________.
Correct Answer: A
Rationale: Liver displaces right kidney lower not heart (left), size, or ribs (protection irrelevant). This explains asymmetry, key for anatomy, contrasting with other causes.
Question 5 of 5
What signal causes the heart to secrete atrial natriuretic hormone?
Correct Answer: A
Rationale: Increased BP triggers ANP release not decreased BP or Na+ changes alone. This links pressure to natriuresis, critical for volume control, contrasting with low-pressure signals.
