What will happen to the urine volume and concentration as the solute gradient in the interstitial space is increased?
Your answer: AS the solute gradient in the interstitial space is increased then the urine volume decreases.
What happened to the volume of urine as the solute concentration in the interstitial space was increased how well did the results compare to your prediction?
How well did the results compare to your prediction? As the solute concentration in the interstitial space was increased, the volume of urine decreased. Most of the tubule filtrate is reabsorbed into the body because the body needs to prevent fluid loss and requires certain solutes to maintain homeostasis.
What would happen to urine volume if you did not add ADH to the collecting duct?
Your answer: The urine volume would increase if ADH was not added to the collecting duct. This is because the ADH work on the collecting ducts where the increase the permeability for water is increased, so less water is secreted into the urine, so urine becomes more concentrated.
What will happen to the urine volume compared with baseline when ADH is added to the collecting duct?
The urine volume will decrease. What will happen to the urine volume ( compared with baseline) when ADH is added to the collecting duct? The water volume in the urinary bladder is decreased, increasing the concentration of solutes such as potassium.
What does ADH do to urine?
Antidiuretic hormone ( ADH ) is a chemical produced in the brain that causes the kidneys to release less water, decreasing the amount of urine produced. A high ADH level causes the body to produce less urine. A low level results in greater urine production.
Which hormone aldosterone or ADH has the greater effect on urine volume?
Antidiuretic hormone ( ADH ) has the greatest effect on urine volume as compared to aldosterone. ADH is responsible for fluid retention.
What happens as the concentration gradient of the interstitial fluid increases?
What effect does the concentration gradient of the interstitial fluid ahve on the maximum urine concentration? Urine concentration EQUALS interstitial fluid concentration. When aldosterone is present, urine volume SLIGHTLY DECREASES as the interstitial gradient increases.
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.
Where does ADH directly alter the urine volume?
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.
Where is most water reabsorbed in the nephron?
The proximal convoluted tubule is where a majority of reabsorption occurs. About 67 percent of the water, Na+, and K+ entering the nephron is reabsorbed in the proximal convoluted tubule and returned to the circulation.
How could the change in urine volume with the increase in blood pressure be seen as beneficial?
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.
What will happen to the glomerular capillary pressure?
What will happen to the glomerular capillary pressure and filtration rate if you decrease the radius of the efferent arteriole? Both pressure and filtration rate will increase. Activation of sympathetic nerves that innervate the kidney leads to a decreased urine production. Pressure increases, but filtration decreases.
Does ADH favor dilute or concentrated 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.
Which of the following is an abnormal constituent of urine?
Abnormal constituents most commonly found in urine are protein (proteinuria) glucose (glycosuria) and acetone (ketonuria), and all may have a significance that must not be ignored.
What would happen to the glomerular filtration rate of a person who experiences a large hemorrhage?
4. What would happen to the glomerular filtration rate of a person who experiences a large hemorrhage? You correctly answered: b. The glomerular filtration rate would decrease.
