Questions On The Urinary System Questions
Question 1 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 2 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.
Question 3 of 5
Efferent arteriole open into;
Correct Answer: A
Rationale: Efferent arteriole feeds peritubular capillaries, not portal vein, arcuate vein, or all. This defines post-glomerular flow, key for reabsorption, contrasting with venous drainage.
Question 4 of 5
Capsular cumulative hydrostatic and colloidal pressure is ;
Correct Answer: B
Rationale: Capsular pressure (hydrostatic ~10-15 mmHg + colloid ~15-20 mmHg) totals ~30 mmHg, not 15, 35, or 45. This sums opposing forces, key for net filtration, contrasting with single values.
Question 5 of 5
Which of the following statements concerning the kidneys is false?
Correct Answer: D
Rationale: Kidneys span T12-L3, not L3-L5 (false), while retroperitoneal, pyramids (8-15), and cortex/medulla are true. This corrects positioning, vital for anatomy, contrasting with true traits.
