Urinary System Test Questions And Answers Questions
Question 1 of 5
In severe acidosis, the kidneys, do all the following EXCEPT:
Correct Answer: B
Rationale: In acidosis, kidneys form ammonia, excrete keto-acids, and reabsorb bicarbonate not excrete it (conserved). This defines renal compensation, critical for pH balance, contrasting with bicarbonate loss.
Question 2 of 5
Peritubular capillary network of the kidney arises from
Correct Answer: B
Rationale: Peritubular capillaries stem from efferent arterioles not afferent, intralobular, interlobular, or arcuate. This specifies post-glomerular flow, critical for reabsorption, contrasting with pre-glomerular sources.
Question 3 of 5
The arterial supply of urinary bladder is derived from all of the following arteries EXCEPT:
Correct Answer: D
Rationale: Bladder supply includes superior/inferior vesical, middle rectal, and obturator not inferior rectal (anus). This corrects vascular anatomy, vital for pelvic surgery, contrasting with rectal supply.
Question 4 of 5
The functional unit of the kidney is called a
Correct Answer: B
Rationale: Nephron (filtration to excretion) is the functional unit not glomerulus (part), corpuscle (subset), or calyx (collecting). This defines renal unit, key for physiology, contrasting with components.
Question 5 of 5
The apex of the renal pyramid is called the:
Correct Answer: C
Rationale: Renal papilla (pyramid apex) drains into calyces not calyx, pelvis, or ureter. This specifies medullary tip, key for collection, contrasting with collecting structures.
