Multiple Choice Questions On Urinary System Questions
Question 1 of 5
Which blood vessel delivers blood to the cortex?
Correct Answer: A
Rationale: Interlobular arteries branch from arcuate to supply cortex, not interlobar (medulla), arcuate (boundary), or efferent (glomerulus). This specifies cortical supply, vital for nephron function, contrasting with other vessels.
Question 2 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 3 of 5
renal cortex is :
Correct Answer: A
Rationale: Renal cortex is the outer layer, not inner (medulla), lateral, or medial (positional). This locates cortex, vital for glomeruli, contrasting with medullary depth.
Question 4 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 5 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.
