Urinary System Mcq Questions Questions
Question 1 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 2 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.
Question 3 of 5
The reason why the right kidney is slightly lower than the left is
Correct Answer: C
Rationale: Liver on right displaces right kidney not heart, size differences. This explains asymmetry, key for anatomy, contrasting with organ size myths.
Question 4 of 5
This is the functional unit of the kidney
Correct Answer: C
Rationale: Nephrons filter/form urine not hilum (entry), neurons (nerve), or medulla (region). This defines functional unit, key for physiology, contrasting with structural terms.
Question 5 of 5
What is the difference between the glomerular filtrate and the plasma?
Correct Answer: B
Rationale: Glomerular filtrate has much less protein than plasma filtration membrane (e.g., podocytes, basement) excludes large proteins (e.g., albumin), unlike plasma's ~7 g/dL. Glucose is present reabsorbed later. Sodium levels are similar freely filtered. More proteins would defy filtration incorrect. Lower protein content distinguishes it, key to filtrate's composition, unlike glucose or sodium errors.
