Urinary System Exam Questions Questions
Question 1 of 5
This happens if the proximal convoluted tubule is removed from nephron
Correct Answer: A
Rationale: PCT removal halts reabsorption (65% filtrate), stopping urine formation, not unaffected, concentrated, or diluted. This underscores PCT's role, critical for filtrate processing, contrasting with later adjustments.
Question 2 of 5
renal corpuscle consist of
Correct Answer: C
Rationale: Renal corpuscle comprises Bowman's capsule and glomerular capillaries, not collecting duct, arteries, or loop. This defines corpuscle, key for filtration, contrasting with tubular parts.
Question 3 of 5
In glomerulus afferent blood vessel is 'arteriole' while efferent is:
Correct Answer: B
Rationale: Efferent vessel is an arteriole, not venule, capillaries, or artery. This specifies glomerular vasculature, key for pressure, contrasting with venous or capillary terms.
Question 4 of 5
Glomerular filteration occurs because of;
Correct Answer: A
Rationale: Hydrostatic pressure drives glomerular filtration, not colloidal (opposes), osmotic (retains), or none. This identifies filtration force, key for GFR, contrasting with opposing pressures.
Question 5 of 5
What portion of the nephron extends into the medulla?
Correct Answer: A
Rationale: Nephron loop (loop of Henle) extends into medulla, not PCT, DCT (cortex), or papillary duct (collecting). This locates medullary segment, critical for concentration, contrasting with cortical parts.
