Clinical Estimation of GFR and Patterns of Clearance

Question 1

Effect of aldosterone and atrial natriuretic factor on sodium clearance

Answer 1

• aldosterone ▶️ ⬆️ Na reabsorption ▶️ ⬇️ Na clearance

- atrial natriuretic factor ▶️ ⬆️ Na excretion (Na diuresis) ▶️ ⬆️ clearance

Question 2

Effect of ADH on urea clearance

Answer 2

⬆️ reabsorption of urea in collecting duct ▶️ ⬆️ BUN plasma ▶️ ⬇️ clearance of urea
