Water reabsorption through the proximal convoluted tubule is termed obligatory water reabsorption, whereas water reabsorption through the distal convoluted tubule is termed facultative water reabsorption. true or false?

True.

Explanation:

Kidneys plays an important role in the urine formation, body's homeostasis and get rid of body from the excretory waste products. Three main process of urine formation are glomerular filtration, absorption and tubular secretion.

The absorption of water in the proximal convoluted tubule is important and necessary for the osmosis maintenance and termed as obligatory water reabsorption. The water reabsorption in  distal convoluted tubule is under the ADH control and termed as  facultative water reabsorption.

Thus, the answer is true.
