A healthy 38-year-old woman is found unconscious and severely dehydrated. Her plasma levels of antidiuretic hormone (ADH) are increased about 5-fold above normal. In which portion of her kidney tubule is most of the water being reabsorbed?

A. Cortical collecting duct
B. Distal tubules
C. Loops of Henle
D. Medullary collecting duct
E. Proximal tubule

I Love Clinical Vignette a concise presentation of an interesting & challenging patient encounter that stimulates an inquisitive learning session.
