Water may be reabsorbed from many regions of the nephron; however, which regions can do so only if the blood levels of ADH are elevated?
A) Proximal and distal tubules
B) Proximal tubule and nephron loop
C) Distal tubule and collecting duct
D) Glomerulus and the glomerular capsule
E) Nephron loop and distal tubule

The distal tubule and collecting duct are the regions of the nephron where water reabsorption is primarily regulated by antidiuretic hormone (ADH). When ADH levels are elevated, these regions become more permeable to water, allowing for increased water reabsorption back into the bloodstream.
