Which part of the nephron is under the control of the hormones ADH and aldosterone?
The distal tubule and collecting duct are the parts of the nephron that are under the control of the hormones ADH (antidiuretic hormone) and aldosterone. These hormones regulate water reabsorption and sodium reabsorption, respectively, in these segments of the nephron.
What is obligatory reabsorption?
the reabsorption of water from pct,alh in nephron which is not influenced by adh.
What is the name of the cells in the nephron that respond to ADH and aldosterone?
The cells in the nephron that respond to ADH are called principal cells, while the cells that respond to aldosterone are called intercalated cells. These cells play a crucial role in regulating the reabsorption of water and electrolytes in the kidneys.
Which region of the nephron does ADH affect water reabsorption?
Antidiuretic hormone (ADH) primarily affects water reabsorption in the collecting ducts of the nephron. It increases the permeability of the collecting ducts to water by promoting the insertion of aquaporin-2 channels in the membranes of the cells lining the ducts. This allows more water to be reabsorbed back into the bloodstream, thereby concentrating the urine and reducing water loss.
What is the terminal part of the nephron?
Papillary duct or DCT The thing in this question that stands out to me is "part of the nephron". Actually the parts of a nephron only include renal corpuscle, proximal convoluted tuble, nephron loop, and distal convoluted tubule. I would a say the answer, if you read it the way I am taking it, is DCT. The papillary duct does follow the DCT but is not part of the nephron.

What is obligatory reabsorption?
the reabsorption of water from pct,alh in nephron which is not influenced by adh.
What is the roleof anti-diuretichormone (ADH)in the body?
ADH makes the collecting duct & distal convoluted tubule of the nephron more permeable to water
What is the role of anti diuretichormone (ADH) in the body?
ADH makes the collecting duct & distal convoluted tubule of the nephron more permeable to water
What is obligatory water reabsorption?
the reabsorption of water from pct,alh in nephron which is not influenced by adh.
What is the role of anti-diuretic hormone (ADH) in the body?
ADH makes the collecting duct & distal convoluted tubule of the nephron more permeable to water
Which area of the nephron is sensitive to ADH?
The area of the nephron that is sensitive to antidiuretic hormone (ADH) is the collecting duct. ADH increases the permeability of the collecting duct to water by promoting the insertion of aquaporin channels in the cell membranes. This allows for greater water reabsorption, which helps concentrate urine and maintain body fluid balance.
What is the name of the cells in the nephron that respond to ADH and aldosterone?
The cells in the nephron that respond to ADH are called principal cells, while the cells that respond to aldosterone are called intercalated cells. These cells play a crucial role in regulating the reabsorption of water and electrolytes in the kidneys.
When the level of ADH increases does less water get reabsorbed by the nephron and collecting duct?
No, when the level of antidiuretic hormone (ADH) increases, more water is reabsorbed by the nephron and collecting duct. ADH enhances the permeability of the collecting ducts to water, allowing more water to be reabsorbed back into the bloodstream. This results in concentrated urine and reduced urine volume. Thus, increased ADH leads to less water being excreted.
The hormone ADH affects reabsorption in the glomerulus?
Antidiuretic hormone (ADH), also known as vasopressin, primarily affects water reabsorption in the kidneys, but it does not directly influence reabsorption in the glomerulus. Instead, ADH acts on the collecting ducts of the nephron, increasing their permeability to water, which enhances water reabsorption back into the bloodstream. This action helps regulate body fluid balance and concentrate urine, particularly in response to dehydration or high osmolarity.
Which component of the nephron does antidiuretic hormone ADH mainly target?
Antidiuretic hormone (ADH), also known as vasopressin, mainly targets the collecting ducts of the nephron. It promotes water reabsorption by increasing the permeability of the duct walls to water, which allows more water to be reabsorbed back into the bloodstream. This action helps to concentrate urine and maintain the body's water balance.
Which region of the nephron does ADH affect water reabsorption?
Antidiuretic hormone (ADH) primarily affects water reabsorption in the collecting ducts of the nephron. It increases the permeability of the collecting ducts to water by promoting the insertion of aquaporin-2 channels in the membranes of the cells lining the ducts. This allows more water to be reabsorbed back into the bloodstream, thereby concentrating the urine and reducing water loss.
