Why does water move out of the collecting duct?
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.
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.
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 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 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

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.
After passing through the proximal convoluted tubule urine filtrate flows where?
Afferent arteriole -> Glomeruli -> Bowman's capsule (ultrafiltration) -> PCT (Highly permeable to water and solutes, brush border enzymes) -> Loop of henle (descending: water permeable, ascending: solute permeable) -> Early PCT (solute permeable) -> Late PCT and cortical collecting duct (principal cell - permeability depends on hormones ADH and aldoesterone and intercalated cell: secrtes H+)-> Medullary collecting duct (principal cell) -> Ureter -> Bladder -> Urethra
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.
