Do you mean collection duct? There are several collection ducts. The main function of this part of the kidney is to help keep the ionic balance and water balance. Water is reabsorbed in the first part of this system and the ions in the more distal part. The hormone ADH regulates the amount of water that it reabsorbed. The kidney needs a high blood pressure to function and so it also regulates that.

What hormones prevents excessive water loss by promoting water reabsorption in the collecting duct?
Antidiuretic hormone (ADH), also known as vasopressin, prevents excessive water loss by promoting water reabsorption in the collecting duct of the kidney. ADH acts on the collecting duct to increase its permeability to water, allowing more water to be reabsorbed back into the bloodstream, thereby concentrating urine and reducing water loss.
The hormone ADH functions to promote water re-abdsorption through the wall of what in the kidney?
ADH promotes water reabsorption through the wall of the collecting duct in the kidney by increasing the permeability of the duct to water. This helps regulate water balance in the body by allowing the reabsorption of water into the bloodstream.
Which substance directly controls the reabsorption of water from the collecting ducts?
Antidiuretic hormone (ADH), also known as vasopressin, directly controls the reabsorption of water from the collecting ducts in the kidneys. ADH acts on the aquaporin water channels in the collecting duct cells to increase water reabsorption back into the bloodstream, helping to concentrate the urine and conserve water.
What is the material called that empties into collecting duct?
Urine formed in the nephron eventually empties into the collecting duct, which is lined with water-permeable cells that help regulate water reabsorption and concentration of urine.
What part of nephron does adh influence?
ADH (antidiuretic hormone) acts on the collecting duct of the nephron in the kidney. It increases the permeability of the collecting duct to water, allowing the reabsorption of more water back into the body, thus concentrating the urine.
Function of the collecting duct of the kidneys?
The collecting duct system is the final component of the kidney to influence the body's electrolyte and fluid balance. In humans, the system accounts for 4-5 percent of the kidney's reabsorption of sodium and 5% of the kidney's reabsorption of water. At times of extreme dehydration, over 24% of the filtered water may be reabsorbed in the collecting duct system. Basically, it collects the urine that a nephron (a unit of kidney that filters) filters.
The collecting duct is impermeable to water in the presence of ADH?
Yes, that's correct. In the absence of antidiuretic hormone (ADH), the collecting duct in the kidneys is impermeable to water, leading to water being excreted in urine. When ADH is present, it causes the collecting duct to become permeable to water, allowing for reabsorption of water back into the body to regulate water balance and concentrate the urine.
The portion of the nephron that attaches to the collecting duct is the?
The portion of the nephron that attaches to the collecting duct is the distal convoluted tubule. It is responsible for fine-tuning the reabsorption of water and electrolytes before the filtrate eventually exits the nephron.
What does the collecting duct do?
The collecting duct is responsible for reabsorbing water and concentrating urine in the final stages of urine formation. It plays a crucial role in maintaining the body's water balance and regulating electrolyte levels by responding to hormonal signals like antidiuretic hormone (ADH) to control water reabsorption.
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.
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.
In which segment of the nephron does tubular fluid have the highest osmolality?
The tubular fluid has the highest osmolality in the medullary collecting duct as water reabsorption occurs in this segment, concentrating the solutes in the tubular fluid.
