Question 1 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.
Question 2 of 5

Question 4 of 5
Glomerular hydrostatic pressure is
Correct Answer: D
Rationale: Glomerular hydrostatic pressure is ~60 mmHg, not 65, 75, or 55. This quantifies filtration pressure, critical for GFR calculation, contrasting with misestimates.
Question 5 of 5
The functional unit of the kidney is called
Correct Answer: B
