Urinary System Mcq Questions Questions
Question 1 of 5
Which of the following is the proper sequence of structures in the nephron?
Correct Answer: C
Rationale: Nephron sequence: glomerulus → PCT → loop → DCT not other orders. This orders filtrate flow, key for processing, contrasting with missequences.
Question 2 of 5
What are the names of the capillaries following the efferent arteriole?
Correct Answer: C
Rationale: Peritubular (cortex) and vasa recta (medulla) follow efferent arteriole not arcuate, interlobar, or medullary alone. This specifies post-glomerular flow, key for reabsorption, contrasting with other vessels.
Question 3 of 5
Progesterone can bind to receptors for which hormone that, when released, activates water retention?
Correct Answer: A
Rationale: Progesterone mimics aldosterone (Na+/water retention) not ADH (water), PTH (Ca2+), or ANH (natriuretic). This specifies cross-reactivity, critical for fluid balance, contrasting with direct water hormones.
Question 4 of 5
Which is found in the highest concentration in the urine?
Correct Answer: B
Rationale: Urea is the most concentrated waste in urine not uric acid, glucose (reabsorbed), or creatinine (less). This identifies excretory priority, critical for nitrogen, contrasting with reabsorbed solutes.
Question 5 of 5
When glucose if found in urine it is called _____.
Correct Answer: A
Rationale: Glucosuria is glucose in urine not uremia (urea), ureteritis (inflammation), or intolerance (metabolic). This defines glycosuria, critical for diabetes, contrasting with other conditions.
