What else can I help you with?
What is obligatory reabsorption?
the reabsorption of water from pct,alh in nephron which is not influenced by adh.
Filtrate reabsorption not under hormonal control is referred to as?
Tubular reabsorption
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.
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.
Is it possible for the kidney to increase water reabsorption without increasing salt absorption Explain?
Yes, it is possible for the kidney to increase water reabsorption without increasing salt absorption. This can occur through the action of antidiuretic hormone (ADH), which promotes the reabsorption of water in the collecting ducts without directly affecting sodium reabsorption. In conditions such as hyperosmolarity, the kidneys can concentrate urine by reabsorbing more water, while sodium levels in the body remain stable. Thus, water reabsorption can be enhanced independently of sodium absorption.

True or false Obligatory water reabsorption involves the movement of water along an osmotic gradient?
True. Obligatory water reabsorption in the kidneys involves the passive movement of water along an osmotic gradient, created by the active reabsorption of solutes like sodium. This process occurs mainly in the proximal convoluted tubule and the descending limb of the loop of Henle.
Filtrate reabsorption not under hormonal control is referred to as?
Tubular reabsorption
Where does water reabsorption occur in the digestive system?
Water reabsorption occurs in the large intestine of the digestive system.
What is obligatory water excretion?
Obligatory water excretion refers to the minimum amount of water that the body needs to eliminate to maintain proper functioning. This is necessary to remove waste products and maintain electrolyte balance. The kidneys regulate obligatory water excretion through processes such as filtration, reabsorption, and secretion.
How does water reabsorption in kidneys occur?
by osmosis through tubular aquaporins

When the kidneys return salts and water to the blood it is called?
Reabsorption via a process called "secretion".
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.
