Urinary System Exam Questions Questions
Question 1 of 5
Concerning the renal lobule, which statement is TRUE?
Correct Answer: D
Rationale: Renal lobule includes a medullary ray and adjacent cortex not pyramid alone, pyramid+cortex (lobe), or inter-pyramid cortex. This defines lobule anatomy, critical for histology, contrasting with lobe or cortex misdefinitions.
Question 2 of 5
Regarding Renal handling of water:
Correct Answer: B
Rationale: Water moves by osmotic diffusion throughout nephron (solute-driven) not PCT-only or ADH-controlled obligatory (PCT inherent). This defines water handling, critical for urine formation, contrasting with restricted or hormonal errors.
Question 3 of 5
Which of the following is the correct sequence in which urine flows through the kidney toward the urinary bladder?
Correct Answer: B
Rationale: Urine flows: papillary duct → minor calyx → major calyx → renal pelvis → ureter not other sequences. This orders drainage, key for urine path, contrasting with misordered flows.
Question 4 of 5
The location of the kidneys in relationship to the peritoneal lining of the abdominal cavity is referred to as
Correct Answer: A
Rationale: Kidneys are retroperitoneal (behind peritoneum) not retroabdominal, posterior (general), or dorsal. This positions kidneys, key for surgery, contrasting with vague terms.
Question 5 of 5
The renal pyramids are separated from each other by extensions of the renal cortex called ________.
Correct Answer: D
Rationale: Renal columns (cortex extensions) separate pyramids not medulla, calyces, or 'medullary cortices.' This defines anatomy, key for structure, contrasting with incorrect terms.
