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.
Is the distal convoluted tubule more permeable to water than solutes?
No, The DCT is impermeable to water. Solutes (Na and Cl) are absorbed from the DCT. As a consequence the osmolality of tubular fluid DECREASES as it moves through the distal convoluted tubule, from ~100mOsm/L at it exits the ascending limb of the loop of Henle to around 70mOsm/L as it enters the collecting duct.
The portion of the nephron that attaches to the collecting duct is the?
loop of henle
What is a common passageway that collects fluid from many neurons?
A collecting duct
A tube that receives urine from the distal convoluted tubule?
Collecting duct
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
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
The collecting duct is impermeable to water in the presence of ADH?
FALSE
What molecule is reabsorbed from the collecting duct so that urine becomes hypertonic?
water
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 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.
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 hormones prevents excessive water loss by promoting water reabsorption in the collecting duct?
antidiuretic hormone
What materials does the collecting duct deliver to the ureter?
The collecting duct delivers urine to the ureter. It contains the toxic waste of the body.
What are the two collecting duct that drain the lymphatic trunks?
Thoracic duct and Right lymphatic duct.The two collecting ducts that drain the lymphatic system are the right and left subclavian veins.Thoracic duct and the right lymphatic duct.
