Multiple Choice Questions On Urinary System Questions
Question 1 of 5
Capillary hydrostatic pressure during filtration is built in the glomerulus as
Correct Answer: D
Rationale: Efferent arteriole's narrowness (vs. afferent) raises glomerular pressure, not Bowman's size/shape or afferent narrowness. This explains filtration pressure, key for GFR, contrasting with structural myths.
Question 2 of 5
Glomerular(Bowman's)capsule double walled cup lined by
Correct Answer: A
Rationale: Bowman's capsule is lined by simple squamous epithelium, not columnar, cuboidal, or stratified. This identifies capsule lining, vital for filtration, contrasting with thicker epithelia.
Question 3 of 5
Glomerular filtration rate (GFR) is
Correct Answer: A
Rationale: GFR is typically 125 mL/min, not 120, 130, or all. This standardizes filtration rate, vital for renal function, contrasting with approximations.
Question 4 of 5
An organ or structure that is not a component of the urinary system is the:
Correct Answer: D
Rationale: Adrenal gland (endocrine) isn't urinary, unlike urethra, bladder, ureter. This excludes non-urinary organs, vital for system definition, contrasting with excretory components.
Question 5 of 5
Which of the following is the correct sequence in which urine flows through the kidney toward the urinary bladder?
Correct Answer: B
Rationale: Urine flows: papillary duct → minor calyx → major calyx → renal pelvis → ureter, not other sequences. This orders urine path, key for drainage, contrasting with misordered flows.
