What happened to the urine volume as the concentration gradient increased?
The urine volume decreased as the concentration gradient increased.
What happens as the concentration gradient of the intersititial fluid increases?
As the concentration gradient of the interstitial fluid increased, the potassium concentration increased and there was a noticeable decrease in urine volume excreted.
Why is it easier to move materials across membranes down a concentration gradient?
osmotic pressure
What acts as a countercurrent exchanger to maintain the osmotic gradient while delivering a nutrient blood supply?
vasa recta
What effect does the concentration gradient of the interstitial fluid have on the maximum urine concentration?
The urine concentration increased.
Is osmotic a diuretic?
Osmotic diuretics are a type of diuretic not a specific drug. Osmotic diuretics work by increasing blood flow to the kidneys and preventing the tubes in the kidneys from making such concentrated urine so that there is no gradient for water to be reabsorbed so you will pee all that water out. An example of an osmotic diuretic is mannitol.
What is the main factor that creates the high osmotic gradient between the cortex and medulla?
A high osmotic gradient between the cortex and the medulla is caused by the running, walking, or jumping of a human person. These simple actions cause the osmotic gradient to rise significantly.
The osmotic gradient ____ as it moves deeper into the medulla?
Increases
Difference between osmotic diuresis and water diuresis?
Osmotic Diuresis Water diuresis *High amount of H2O reabsoebed in *Normal absorption. PCT. *A lot of solutes are lost. *loss of solute amount is less. *Very high amounts of urine are *Amounts of urine produced are less produced. than that in osmotic diuresis. *Low medullary osmolality. *High medullary osmolality. *Normal *The limiting concentration gradient *The limiting gradient is not reached. for Na is reached at PCT. *Hyponatremia may occur. *Takes more time to get hyponatremia.
What happened to the urine volume as the concentration gradient increased?
The urine volume decreased as the concentration gradient increased.
What happens as the concentration gradient of the intersititial fluid increases?
As the concentration gradient of the interstitial fluid increased, the potassium concentration increased and there was a noticeable decrease in urine volume excreted.
Why is it easier to move materials across membranes down a concentration gradient?
osmotic pressure
The mechanism that establishes the medullary osmotic gradient depends most on the permeability properties of the?
loop of Henle
Which term describes describes the difference in the concentration of a substance across a cells membrane?
This is called the osmotic gradient.
True or false Obligatory water reabsorption involves the movement of water along an osmotic gradient?
false
Which term describes the difference in the concentration of a substance across a cells membrane?
concentration gradient
Pressure is equal to the tendency of water to enter one solution from another due to a concentration gradient?
Osmotic Pressure
