Water moves out of the collecting duct in the kidney due to the action of antidiuretic hormone (ADH), also known as vasopressin. ADH increases the permeability of the collecting duct to water, allowing water to be reabsorbed back into the bloodstream, thus concentrating the urine.
What else can I help you with?
Why does the concentration of urea increase in the collecting duct?
The collecting duct is responsible for reabsorbing water in response to antidiuretic hormone (ADH). When water is reabsorbed, urea becomes more concentrated in the filtrate that remains in the collecting duct, leading to an increase in its concentration.
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.
Is the collecting duct the site that drains the distal convoluted tubule?
No, the collecting duct is the site where the filtrate from multiple nephrons is collected and the final adjustments to urine concentration are made. The distal convoluted tubule drains into the collecting duct.
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.
A tube that receives urine from the distal convoluted tubule?
The tube that receives urine from the distal convoluted tubule is called the collecting duct. It plays a crucial role in reabsorbing water and concentrating the urine before it is excreted from the body.
Structure of collecting duct?
The collecting duct is a part of the nephron in the kidney that receives urine from the distal convoluted tubule. It plays a key role in reabsorbing water and sodium to help maintain fluid balance in the body. The collecting duct is composed of two main segments - the cortical collecting duct and the medullary collecting duct.
Why does the concentration of urea increase in the collecting duct?
The collecting duct is responsible for reabsorbing water in response to antidiuretic hormone (ADH). When water is reabsorbed, urea becomes more concentrated in the filtrate that remains in the collecting duct, leading to an increase in its concentration.
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.
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 molecule is reabsorbed from the collecting duct so that urine becomes hypertonic?
water
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.
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.
What is a collecting duct in the kidneys?
The collecting duct is a part of the kidney nephron responsible for reabsorbing water and concentrating urine. It plays a crucial role in regulating the body's fluid balance and maintaining blood pressure. The collecting duct connects multiple nephrons to the ureters for the elimination of concentrated urine from the body.
Is the collecting duct the site that drains the distal convoluted tubule?
No, the collecting duct is the site where the filtrate from multiple nephrons is collected and the final adjustments to urine concentration are made. The distal convoluted tubule drains into the collecting duct.
What is the correct order an excreted water molecule moves from glomerulus to collecting duct?
It goes from the glomerulus to the bowman's capsule, to the proximal convoluted tubule, to the loop of henle, to the distal convoluted tubule, to the collecting duct.
What is osmoregulators?
osmoregulation is the regulation of water content in the body. It controls the permiability of the walls of the collecting duct.
What is the function of the collecting duct?
The collecting duct in the kidney plays a crucial role in reabsorbing water and concentrating urine by responding to the hormone ADH. It helps regulate the body's water balance by either concentrating or diluting urine based on the body's hydration status.
