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
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.
Where does obligatory water reabsorption occur?
Obligatory water reabsorption occurs in the proximal convoluted tubule of the nephron in the kidney. This process helps to maintain the body's water balance by reabsorbing a majority of the filtered water back into the bloodstream.
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 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.
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.
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.
Which hormone is responsible for facultative water reabsorption in the collecting ducts?
ADH is the hormone responsible for facultative water reabsorption.
What is facultative water reabsorption?
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.
When blood pressure decrease to promote the reabsorption of water is?
the renal hormonesecreted by the hypothalmus when blood pressure decrease to promote the reabsorption of water is
