The kidneys reabsorb more water primarily in response to the hormone antidiuretic hormone (ADH), also known as vasopressin. When the body is dehydrated or the blood osmolarity increases, ADH is released from the pituitary gland, prompting the kidneys to increase water reabsorption in the collecting ducts. This process helps concentrate urine and maintain fluid balance in the body. Additionally, factors like low blood volume or pressure can also stimulate ADH release, enhancing water reabsorption.
What else can I help you with?
What tells the kidneys how much water to absorb?
Antidiuretic hormone ADH
What is an example of high concentrations of salt in your blood cause your kidneys to reabsorb water?
When there are high concentrations of salt in the blood, a condition known as hypernatremia occurs. This triggers the release of antidiuretic hormone (ADH) from the pituitary gland, which signals the kidneys to reabsorb more water from the urine back into the bloodstream. This process helps dilute the salt concentration in the blood, restoring balance and preventing dehydration. Consequently, the body retains water to maintain homeostasis in response to the increased salt levels.
Rising blood levels of aldosterone cause the kidney tubules to?
To reabsorb more sodium and some tme that can lead to an edema (oedema)
If you forget your water bottle when you go for a long walk on a warm day what signal would most likely be sent to your kidneys?
If you forget your water bottle during a long walk on a warm day, your body will likely become dehydrated. In response, your kidneys would receive signals to conserve water by releasing the hormone vasopressin (also known as antidiuretic hormone, ADH). This hormone prompts the kidneys to reabsorb more water from the urine, reducing urine output and helping to maintain hydration levels. Additionally, the kidneys may also signal thirst to encourage you to drink more fluids.
What event occurs under maximum ADH stimulation?
Under maximum ADH (antidiuretic hormone) stimulation, the kidneys reabsorb more water from the urine, leading to concentrated urine production and reduced urine output. This helps to conserve body water and maintain hydration levels.
What makes the kidneys absorb more water?
The kidneys absorb more water when the hormone vasopressin signals the kidneys to reabsorb water back into the bloodstream. This occurs when the body needs to conserve water or is in a state of dehydration.
What tells the kidneys how much water to absorb?
Antidiuretic hormone ADH
What hormone stimulates the kidneys to reabsorb more water?
ADH- when the body is dehydrated, ADH helps reduce more water loss
What are the effects of ADH on water balance in the blood?
Antidiuretic hormone (ADH) helps regulate water balance in the blood by increasing the permeability of the kidneys to water, allowing them to reabsorb more water back into the bloodstream. This helps in conserving water and concentrating the urine, ultimately reducing the amount of water lost in urine and maintaining blood volume and pressure within a narrow range.
What is an example of high concentrations of salt in your blood cause your kidneys to reabsorb water?

This process helps dilute the salt concentration in the blood, restoring balance and preventing dehydration. Consequently, the body retains water to maintain homeostasis in response to the increased salt levels.
What of the Kidneys?
Tubules are the tubes running through each little (microscopic) nephrons within each kidney that aid in filtering and collecting of the waste products, and then depending on how much water is in the body it either can reabsorb more water or more salt depending on your electrolyte balance. :-D
Rising blood levels of aldosterone cause the kidney tubules to?
To reabsorb more sodium and some tme that can lead to an edema (oedema)

In the exchange reaction in which the kidneys secrete H ions into the urine and reabsorb Na from the urine what happens?
make the urine more acidic while adding buffers to the blood
What event occurs under maximum ADH stimulation?
Under maximum ADH (antidiuretic hormone) stimulation, the kidneys reabsorb more water from the urine, leading to concentrated urine production and reduced urine output. This helps to conserve body water and maintain hydration levels.
What contains more water the blood going into the kidneys or the blood leaving it?
Blood entering the kidneys has more water; the water is extracted by the kidneys and sent through the ureter to the bladder.
What happends when ADH increases?
When antidiuretic hormone (ADH) increases, it causes the kidneys to reabsorb more water, leading to a decrease in urine output and more concentrated urine. This helps to maintain fluid balance in the body by conserving water and preventing dehydration.
