Urinary System Mcq Questions Questions
Question 1 of 5
The kidney secretes for the purpose of stimulating bone marrow activity.
Correct Answer: C
Rationale: Erythropoietin from kidneys boosts RBC production, not renin (pressure), aldosterone (sodium), or somatomedin (growth). This defines hematopoietic role, key for anemia, contrasting with RAAS hormones.
Question 2 of 5
The renal corpuscle is comprised of a glomerulus and
Correct Answer: B
Rationale: Renal corpuscle includes glomerulus and Bowman's capsule, not PCT, loop, or DCT (tubular). This defines filtration unit, key for GFR, contrasting with tubular segments.
Question 3 of 5
This substance cannot pass through semi permeable walls of glomerulus
Correct Answer: D
Rationale: Globin, albumin (proteins), and blood cells are too large for glomerular filtration all apply. This defines filtration barrier, critical for plasma selectivity, contrasting with small solutes.
Question 4 of 5
This artery passes blood to the kidney
Correct Answer: C
Rationale: Renal artery supplies the kidney, not iliac (pelvis), cystic (bladder), or celiac (gut). This identifies renal blood flow, critical for perfusion, contrasting with other arteries.
Question 5 of 5
