Urinary System Questions Questions
Question 1 of 5
Which of the following occurred by active transport?
Correct Answer: D
Rationale: Amino acid reabsorption in PCT uses active transport (Na+-linked), not albumin/creatinine (filtration) or water (osmosis). This distinguishes active mechanisms, critical for nutrient retention, contrasting with passive processes.
Question 2 of 5
The compound used to assess the function of the kidney at the level of the glomerulus is
Correct Answer: A
Rationale: Creatinine clearance measures GFR, not insulin (metabolism), PAH (tubular secretion), or creatine (precursor). This identifies glomerular marker, critical for renal assessment, contrasting with tubular tests.
Question 3 of 5
What is the function of the renal system?
Correct Answer: D
Rationale: Renal system regulates pH (H+ excretion), blood pressure (RAAS), and concentration (water/solute) all apply. This encompasses renal roles, critical for homeostasis, contrasting with single functions.
Question 4 of 5
What affect does ADH have on urine output?
Correct Answer: C
Rationale: ADH reduces urine output by increasing water reabsorption, not minimal, increases, or maintains. This specifies ADH's antidiuretic role, critical for hydration, contrasting with diuretic effects.
Question 5 of 5
This is the activity of Atrial Natriuretic peptide (ANP)
Correct Answer: D
Rationale: ANP inhibits aldosterone/ADH, reducing water/sodium reabsorption all apply. This defines natriuretic effect, key for volume reduction, contrasting with single actions.
