Question

Most water is reabsorbed from the filtrate in the

a. proximal convoluted tubule
b. descending loop of Henle
c. ascending loop of Henle d. distal convoluted tubule

Answer 1

The answer is B. descending loop of henle.

Step-by-step explanation:

Most of the filtrate water is reabsorbed at the level of the DESCENDING LOOP OF HENLE. This branch has a wide cortical zone and an extreme spinal cord; It has low permeability to ions and urea, but is very permeable to water; there are a few channels of aquapurine type 1 that absorb 20% of the filtered water.
