Urinary System Mcq Questions Questions
Question 1 of 5
renal pyramids are surrounded by lobe .so every kidney has.
Correct Answer: A
Rationale: Kidneys have 6-12 lobes (pyramids + cortex), not fewer or none. This quantifies lobar structure, key for anatomy, contrasting with undercounts.
Question 2 of 5
If GFR is 125 ml/min.how much fluid our kidney filters in 24 hrs.
Correct Answer: A
Rationale: 125 mL/min × 1440 min = 180 L/day, not 160, 130, or 120. This calculates daily filtration, key for fluid dynamics, contrasting with underestimates.
Question 3 of 5
The kidneys are:
Correct Answer: D
Rationale: Kidneys regulate volume (water), pressure (RAAS), pH (H+) all apply. This encompasses renal functions, critical for homeostasis, contrasting with single roles.
Question 4 of 5
Which of the following statements concerning the ureters is false?
Correct Answer: D
Rationale: Ureters are retroperitoneal, not intraperitoneal (false), while epithelium, tunics, and peristalsis are true. This corrects ureter position, vital for anatomy, contrasting with true features.
Question 5 of 5
The triangular area of the urinary bladder between the two ureters posteriorly and the urethra anteriorly is the
Correct Answer: D
Rationale: Trigone is the bladder's triangular area (ureters to urethra), not sphincters or muscle (mislisted as D). This defines bladder base, vital for anatomy, contrasting with control structures.
