Question

Which of the following statement is false?

(a) 20% to 25% of all sodium is reabsorbed into the bloodstream in the loop of Henle

(b) 5% to 10% of sodium is reabsorbed in the distal tubules

(c) 3% sodium is absorbed in collecting ducts

(d) 50% of sodium is absorbed in the glomerulus

I got this question in examination.

My doubt is from Diuretics in section Applications of Pharmacokinetic Principles, Diuretics, Drug Concentration and Pharmacologic Response of Drug Biotechnology

Answer 1

Right option is (d) 50% of sodium is absorbed in the glomerulus

The best I can explain: We are aware of the fact that where sodium goes water follows. 20-25% of all sodium is reabsorbed into the bloodstream in the loop of Henle. 5-10% gets reabsorbed in the distal tubes and 3% of the sodium gets reabsorbed in collecting ducts. Thus is sodium is not reabsorbed, water will also not get reabsorbed thus making water excreted as urine.
