Questions On The Urinary System Questions
Question 1 of 5
Which condition is characterized by abnormally low urine output?
Correct Answer: A
Rationale: Oliguria is low output (<400 mL/day) not polyuria (excess), anuria (<50 mL), or glycosuria (glucose). This identifies reduced flow, key for renal assessment, contrasting with excess or unrelated terms.
Question 2 of 5
All of the following are TRUE about the juxta-glomerular cells EXCEPT
Correct Answer: B
Rationale: JG cells are in afferent arterioles not DCT (macula densa); other traits (smooth muscle, innervation, RER/Golgi) are true. This corrects location, key for renin secretion, contrasting with DCT misplacement.
Question 3 of 5
Mesangial cells are
Correct Answer: E
Rationale: Mesangial cells are pericytes, contract, have receptors (AII, ANF), and phagocytose all true. This comprehensively describes their role, critical for glomerular dynamics, contrasting with partial functions.
Question 4 of 5
Cells lining the renal collecting ducts and tubules include
Correct Answer: D
Rationale: Collecting ducts have principal (water) and intercalated (acid-base) cells not lacis (JGA). This specifies cell types, critical for concentration, contrasting with JGA inclusion.
Question 5 of 5
The arteriolar recta spuria arise from
Correct Answer: D
Rationale: Arteriola recta spuria (false) arise from efferent arterioles not interlobar, interlobular, or afferent. This specifies medullary supply, critical for countercurrent, contrasting with other origins.
