Urinary System Test Questions And Answers Questions
Question 1 of 5
Wilm's tumor is characterized by the followings EXCEPT:
Correct Answer: C
Rationale: Wilms' tumor (nephroblastoma) affects infants, presents as a mass, is bilateral in ~7%, and often metastasizes to lungs not rarely. This corrects tumor behavior, vital for oncology, contrasting with metastasis rarity.
Question 2 of 5
Failure of complete union between the ureteric bud and the metanephric cap leads to:
Correct Answer: A
Rationale: Incomplete ureteric bud-metanephric fusion causes double ureter not polycystic, pelvic, lobulation, or horseshoe (fusion anomalies). This defines congenital defect, critical for urology, contrasting with other malformations.
Question 3 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 4 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 5 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.
