Questions On The Urinary System Questions
Question 1 of 5
The renal pyramids are located within the
Correct Answer: C
Rationale: Renal pyramids reside in the medulla, not columns, cortex, or pelvis (collecting). This locates pyramids, key for concentrating urine, contrasting with cortical structures.
Question 2 of 5
How much of the cardiac output passes through the kidneys?
Correct Answer: B
Rationale: Kidneys receive ~25% of cardiac output (1.2 L/min), not 10%, 50%, or 65%. This quantifies renal perfusion, key for filtration, contrasting with under/overestimations.
Question 3 of 5
Where does ADH have its greatest effect?
Correct Answer: C
Rationale: ADH primarily acts on DCT and collecting duct (via aquaporins), not loop, PCT, or glomerulus. 'C' fits DCT focus here. This locates ADH action, key for urine concentration, contrasting with filtration sites.
Question 4 of 5
The total number of orifices for outgoing and incoming of urine through the bladder is
Correct Answer: B
Rationale: Bladder has 3 orifices: 2 ureters (in), 1 urethra (out), not 2, 4, or 5. This counts bladder openings, vital for anatomy, contrasting with miscounts.
Question 5 of 5
vessels, ureters and nerves enter and leave the kidney through;
Correct Answer: D
Rationale: Hilus is the kidney's entry/exit point, not mediastinum (chest), chondrocyte (cartilage), or cortex (region). This specifies renal access, key for anatomy, contrasting with mislocations.
