What hormone affect the concentration of k ions?
Aldosterone is a hormone that affects the concentration of potassium ions in the body. It is produced by the adrenal glands and regulates the levels of sodium and potassium in the blood, leading to increased reabsorption of sodium and excretion of potassium by the kidneys.
Hormones stimulating water conservation in the kidneys?
The hormone that stimulates water conservation in the kidneys is called antidiuretic hormone (ADH), also known as vasopressin. ADH acts on the kidneys to increase water reabsorption, resulting in concentrated urine production and decreased water excretion. This process helps to maintain fluid balance and prevent dehydration in the body.
Why does the concentration of potassium change in the presence of ADH without a change in the excretion of potassium?
ADH makes the distal tubule and collecting duct more permiable to water so body will reabsorb more water from the filtrate. It does not require excretion of potassium because it is not reabsorbing sodium at the expense of losing potassium like the hormone aldosterone would in the same case.
Dilution or concentration of urine is determined by the availibility of?
The concentration of urine is determined by the availability of antidiuretic hormone (ADH), which regulates water reabsorption in the kidneys. When ADH is present, urine becomes concentrated. Conversely, dilute urine results when ADH levels are low, leading to increased water excretion by the kidneys.
What is a condition caused by insufficient production of the antidiuretic hormone or by the inability of the kidneys to respond to the antidiuretic hormone?
Diabetes insipidus.
Which hormone aids in sodium conservation and potassium excretion?
antidiuretic hormone
What hormone affect the concentration of k ions?
Aldosterone is a hormone that affects the concentration of potassium ions in the body. It is produced by the adrenal glands and regulates the levels of sodium and potassium in the blood, leading to increased reabsorption of sodium and excretion of potassium by the kidneys.
When Antidiuretic hormone is present urine concentration equals interstitial fluid concentration?
True
How does ADH affect the concentration of potassium in urine?
ADH, or antidiuretic hormone, increases water reabsorption in the kidneys, leading to more concentrated urine. As water is reabsorbed, the concentration of solutes in the urine, including potassium, increases. Therefore, ADH indirectly affects the concentration of potassium in urine by influencing the overall concentration of solutes.

What two hormones regulate water balance?
Antidiuretic hormone (ADH) and aldosterone are the two hormones that regulate water balance in the body. ADH helps the kidneys retain water by increasing water reabsorption, while aldosterone regulates water and salt balance by promoting sodium reabsorption and potassium excretion in the kidneys.
Dilution or concentration of urine is determined by the availibility of?
The concentration of urine is determined by the availability of antidiuretic hormone (ADH), which regulates water reabsorption in the kidneys. When ADH is present, urine becomes concentrated. Conversely, dilute urine results when ADH levels are low, leading to increased water excretion by the kidneys.
Which hormone keeps both the fluid level of the body and blood pressure form decreasing?
Antidiuretic hormone.
What hormones is also called the antidiuretic hormone?
It stimulates water reabsorption by the kidneys
How are sodium and potassium levels controlled in the body?
Sodium and potassium levels in the body are primarily regulated by the kidneys through filtration and reabsorption processes. Hormones like aldosterone and antidiuretic hormone play a crucial role in these mechanisms, helping to maintain electrolyte balance by adjusting their retention or excretion. Additionally, dietary intake and fluid balance also influence the levels of sodium and potassium in the body.
What part of the brain is involved in control of antidiuretic hormone?
The Posterior Pituitary secretes oxytocin and vasopressin, which is antidiuretic hormone.
