facultative water reabsorption is the reabsorption of water in the kidneys that is under the hormonal control of ADH (anti diuretic hormone)

The amount of water reabsorbed is dependant on how much the body needs to reabsorb to maintain homeostasis and fluid balance.

What hormone is responsible for faculative water reabsorption?

Antidiuretic hormone (ADH), also known as vasopressin, is responsible for facultative water reabsorption in the kidneys. Its release is controlled by the body's hydration levels to regulate water balance by increasing the permeability of the collecting ducts in the kidneys.


How does sodium reabsorption affect water reabsorption?

Sodium reabsorption in the kidneys creates an osmotic gradient that drives water reabsorption. As sodium is reabsorbed into the bloodstream, water follows it to maintain the body's electrolyte balance and fluid volume. Therefore, sodium reabsorption directly influences the reabsorption of water in the kidneys.

What regulates water reabsorption in the distal convoluted tubules?

The hormone aldosterone regulates water reabsorption in the distal convoluted tubules. It works by increasing the reabsorption of sodium ions, which in turn triggers the reabsorption of water from the tubules back into the bloodstream.


What structure is important for the reabsorption of water?

The loop of Henle in the nephron is important for the reabsorption of water in the kidney. It creates a concentration gradient in the kidney medulla, allowing for the reabsorption of water back into the bloodstream.

Where does most water reabsorption occur?

Most water reabsorption in the body occurs in the proximal convoluted tubule of the kidney. This is the first part of the nephron where water is reabsorbed back into the bloodstream.
