What else can I help you with?
Where does ADH act on the nephron?
collecting duct (system) and late distal tubule
What is reabsorbed in the collecting ducts of the kidneys?
yes
What forms the collecting ducts converge as they extend toward the calyces?
The collecting ducts converge to form larger ducts known as papillary ducts. These papillary ducts then empty urine into the renal calyces, which are part of the renal pelvis where urine collects before being drained into the ureters.
Which structures drains into the collecting ducts?
Loop of henle
Renal pyramids are?
collecting ducts and uriniferous tubules
What substance directly controls the reabsorption of water from the collecting ducts?
The antidiuretic hormone is the substance that directly controls the reabsorption of water from the collecting ducts. It is also known as vasopressin.
What do the walls of the collecting ducts have variable permeability to?
The walls of the collecting ducts have variable permeability to water and urea. This allows the kidneys to adjust the concentration of urine depending on the body's hydration levels.
Where do the ureters lead to?
They some what lead to the collecting ducts which ducks that collect.
What does collecting ducts converging as they extend toward the calyces form?
pevis
Lymph drainage from collecting ducts enters what vein?
lymph drainage ducts enters what veins?
What makes collecting ducts permeable to water?
The collecting ducts are permeable to water due to the presence of aquaporin water channels in their cell membranes. These channels allow water to pass through the cells and be reabsorbed back into the bloodstream under the influence of antidiuretic hormone (ADH). Without aquaporins, water reabsorption in the collecting ducts would be hindered.
What would be a reasonable mechanism for diuretics?
Loop diuretics work by restraining the sodium-potassium-chloride cotransporter. Thiazide diuretics restrain the sodium-chloride transporter. Carbonic anhydrase inhibiting diuretics work by restraining bicarbonate transport.
