What will happen to the urine volume and the urine concentration (compared with baseline) in the presence of both aldosterone and ADH? Urine volume will decrease and concentration will increase.
What will happen to the urine volume when ADH is added?
ADH increases the permeability to water of the distal convoluted tubule and collecting duct, which are normally impermeable to water. This effect causes increased water reabsorption and retention and decreases the volume of urine produced relative to its ion content.
What will happen to the urine volume compared with baseline when aldosterone is added to the distal tubule?
What will happen to the urine volume (compared with baseline) when aldosterone is added to the distal tubule? The urine volume will decrease. … The water volume in the urinary bladder is decreased, increasing the concentration of solutes such as potassium.
What happened to urine volume and concentration in the presence of aldosterone?
HOW DID ALDOSTERONE AFFECT THE URINE VOLUME? WHEN ALDOSTERONE IS PRESENT, URINE VOLUME SLIGHTLY DECREASED AS THE INTERSTITIAL GRADIENT INCREASES.
What happened to the urine volume when the solute gradient in the interstitial space was increased?
What happened to the urine concentration when the solute gradient in the interstitial space was increased? The urine concentration stayed the same.
Why does ADH affect urine volume?
The principal determinant for the release of ADH from the posterior pituitary gland is an increase in the osmolarity of the body fluid will stimulate more release of ADH. … ADH has the greater effect on urine volume because it causes a higher decrease in the amount of volume.
Why does ADH favor dilute urine?
Does ADH favor the formation of dilute or concentrated urine? ADH favors formation of concentrated urine because ADH causes an increase of water permeability in the DCT and collecting ducts. Water moves from these tubules into the interstitial fluid by osmosis. … The concentration gradient limits the urine concentration.
What will happen to the glomerular capillary pressure and filtration rate if you increase?
7. Describe the effect of increasing the efferent radius on glomerular capillary pressure and filtration rate. Your answer: If we increase the efferent radius the capillary pressure and filtration rate will decrease.
How could increased urine volume be viewed as beneficial to the body?
The glomerular capillary pressure and filtration rate increased. … How could a change in urine volume with the increase in blood pressure be viewed as being beneficial to the body? Increased blood pressure can be a result of increased blood volume, and increase in urine volume would stabilize blood volume.
Why does ADH affect potassium?
Both of these are enhanced primarily by aldosterone, and also by ADH (by decreasing urine flow, ADH reduces K secretion, but by increasing luminal permeability, ADH promotes it) and by dietary K excess.
Which hormone aldosterone or ADH has the greater effect on urine volume?
ADH has the greater effect on urine volume. ADH is responsible for fluid retention. Aldosterone is primarily increasing sodium uptake and potassium secretion. … In order to reabsorb sodium without affecting urine volume, you would need to increase the amount of aldosterone and decrease ADH.
What does ADH hormone do?
Antidiuretic hormone (ADH), also called arginine vasopressin (AVP), is a hormone that helps regulate water balance in the body by controlling the amount of water the kidneys reabsorb while they are filtering wastes out of the blood.
At which concentration of glucose carriers was the glucose concentration reduced to zero?
Calculate the Price
|What are the two main parts of the nephron?||the renal corpuscle and the renal tubule|
|At which concentration of glucose carriers was the glucose concentration reduced to zero?||400|
Is most of tubule filtrate reabsorbed in body or excreted in urine?
About 99% of the water-like filtrate , small molecules, and lipid-soluble substances , are reabsorbed downstream in the nephron tubule. This means that the amount of urine eliminated is only about one percent of the amount of fluid filtrated through the glomeruli into the renal tubules.
What happened to urine volume and concentration as you increased ISF concentration explain?
What happened to urine concentration when ISF [solute] was increased? … -urine would go up. Lack of ADH would prevent collecting duct from absorbing water. All that water stays in urine which makes more urine volume.
