Urinary System Multiple Choice Questions Questions
Question 1 of 5
The process of urine formation includes:
Correct Answer: A
Rationale: Urine forms via filtration (glomerulus), reabsorption (tubules), and secretion (tubules) not digestive or GI processes. This outlines nephron function, critical for waste removal, contrasting with unrelated mechanisms.
Question 2 of 5
The amount of urine normally produced per day is approximately:
Correct Answer: C
Rationale: Normal urine output is 1-2 L/day not lower (oliguria) or higher (polyuria). This quantifies healthy production, critical for assessing function, contrasting with abnormal volumes.
Question 3 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 4 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 5 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.
