Glands of Littre's

Correct Answer: D

Rationale: Glands of Littre are mucous-secreting, prominent in male penile urethra, and present in female urethra all true. This describes urethral glands, key for lubrication, contrasting with partial traits.

Correct Answer: D

Rationale: Ureteric bud forms collecting tubules, minor/major calyces all urinary collecting structures via branching with the metanephric cap. 'All' reflects its full role, critical for kidney drainage, contrasting with partial calyceal focus.

Correct Answer: A

Rationale: Bladder (vesicourethral canal) is endodermal not mesodermal (trigone), ectodermal, all, or mixed; cloacal endoderm forms it. This defines germ layer, key for embryology, contrasting with mesodermal trigone.

Correct Answer: D

Rationale: The urinary system doesn't preserve water-sugar balance regulates water, electrolytes, not glucose (e.g., PCT reabsorbs all glucose). Blood pressure maintenance via renin true. Metabolic waste excretion (urea) core function. Acid-base balance via H /HCO₃⁻ correct. Water-sugar misaligns glucose isn't urinary-regulated distinguishing it, key to urinary specificity, unlike established roles.

Correct Answer: B

Rationale: Order is kidneys (production), ureters (transport), bladder (storage), urethra (excretion) e.g., anatomical flow. Urethra before bladder reverses impossible. Bladder first ignores production false. Correct sequence distinguishes it, key to urinary path, unlike disordered options.
