Urinary System Multiple Choice Questions Questions
Question 1 of 5
The normal pH of urine is:
Correct Answer: A
Rationale: Normal urine pH is ~6.0 (slightly acidic) not neutral, alkaline, or strongly acidic (pathological). This defines typical acidity, critical for urinalysis, contrasting with abnormal ranges.
Question 2 of 5
Podocytes are
Correct Answer: D
Rationale: Podocytes are visceral epithelial cells of Bowman's capsule, forming filtration slits not endothelial (capillaries), parietal (outer layer), or mesangial (support). This identifies their role in the filtration barrier, critical for GFR, contrasting with other glomerular cells.
Question 3 of 5
The distal convoluted tubules of the kidney
Correct Answer: A
Rationale: Distal convoluted tubules (DCT) are simple cuboidal not brush border (PCT), lacking basement (false), or RER-rich (mitochondria-rich). This defines DCT structure, critical for fine-tuning, contrasting with PCT features.
Question 4 of 5
Mesangial cells
Correct Answer: D
Rationale: Mesangial cells phagocytose basement membrane not restricted (extra-glomerular exist), parietal (podocytes), or creatinine-secreting. This specifies their role, critical for GBM maintenance, contrasting with incorrect functions.
Question 5 of 5
Lacis cells are
Correct Answer: B
Rationale: Lacis cells are extra-glomerular mesangial cells in the JGA not secretory, intra-glomerular, or neuroepithelial. This specifies their identity, key for JGA support, contrasting with other cell types.
