Urinary System Multiple Choice Questions Questions
Question 1 of 5
Blood in the arcuate arteries flows next into the:
Correct Answer: C
Rationale: Arcuate arteries supply interlobular arteries not afferent (next), efferent (post-glomerular), interlobar (prior), or stellate (cortical veins). This repeats Q29, key for flow, contrasting with missteps.
Question 2 of 5
The kidney ascends from the pelvis to the upper lumbar region as a result of:
Correct Answer: B
Rationale: Kidney ascent is driven by lumbar/sacral growth not ureteric elongation (forms collecting system), cap migration, or all; 'b' fits best. This explains positional shift, critical for anatomy, contrasting with mechanical or combined causes.
Question 3 of 5
The male urethra is:
Correct Answer: D
Rationale: Male urethra has endodermal (vesicourethral, sinus) and ectodermal (glans) origins not just one or mesodermal alone; 'all' fits broadly. This reflects mixed lineage, critical for urethral development, contrasting with single-layer views.
Question 4 of 5
Which of the following is NOT a nitrogenous waste excreted by the kidneys?
Correct Answer: A
Rationale: Amino acids aren't nitrogenous wastes reabsorbed or metabolized, not excreted (e.g., PCT). Urea, from protein breakdown major waste. Uric acid, from purines excreted. Creatinine, from muscle waste product. Amino acids' conservation distinguishes them, critical for nitrogen reuse, unlike waste products excreted.
Question 5 of 5
The depression of the kidney where the renal artery enters and the renal vein and ureters exit is called the:
Correct Answer: A
Rationale: The hilum is the kidney's depression entry/exit for artery, vein, ureter (e.g., medial notch). Capsule is protective not an opening. Cortex is nephron-rich internal. Pyramid is medullary not entry. Hilum's gateway role distinguishes it, critical for vascular/urinary access, unlike structural zones.
