Questions On The Urinary System Questions
Question 1 of 5
Which of these could appear in the urine from dieting or the utilization of excess lipids?
Correct Answer: D
Rationale: Ketones appear in urine during fat breakdown (ketosis), not urea (protein), uric acid (purine), or glycine (amino acid). This highlights ketonuria, key for metabolic states, contrasting with nitrogenous waste.
Question 2 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 3 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 4 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.
Question 5 of 5
Reabsorption and secretion occurs between ;
Correct Answer: B
Rationale: Reabsorption/secretion occurs between vasa recta and renal tubule, not collecting duct alone, ureter, or all. This specifies exchange site, key for solute movement, contrasting with broader options.
