Question

What is the effect of ADH on renal tubules?

Answer 1

Antidiuretic hormone stimulates waterreabsorbtion by stimulating insertion of "water channels" or aquaporins into the membranes of kidney tubules. These channels transport solute-freewater through tubular cells and back into blood, leading to a decrease in plasma osmolarity and an increase osmolarity of urine.
