Question

Compare obligatory water reabsorption with facultative water reabsorption

Answer 1

Explanation:

Water reabsorption together with solutes in tubular fluid is called obligatory water reabsorption. Reabsorption of the final water, facultative reabsorption, is based on need and occurs in the collecting ducts and is regulated by ADH.

Answer 2

Answer:

The obligatory water reabsorption is free from antidiuretic hormone influence while the facultative water reabsorption is depend on the influence of antidiuretic  hormone.

Explanation:

What is obligatory water reabsorption?

• It is a water reabsorption process which is independent from the antidiuretic hormone or also known as vasopressin.

• It works in continue manner without any interference.  

• The reabsorption of water in earlier part of nephron is obligatory water reabsorption.

What is facultative water reabsorption?

• It is a reabsorption of water from urine from the collecting ducts of nephrons which is influenced by the release of vasopressin or antidiuretic (ADH) hormone.

• This process decreases the volume of urine and prevents diuresis.

• This process only occurs when vasopressin or ADH is released.

So, the main difference between obligatory water reabsorption and facultative water reabsorption is that the obligatory water reabsorption is free from the influence of ADH while the facultative water absorption is dependent of ADH.
