New cards
What type of fluid is the loop of henle responsible for producing?
Hypo or hyperosmotic fluid depending on the water needs of the body
2
New cards
What is reabsorbed in the thing descending loop?
Water
3
New cards
Is the water hypo or hyperosmotic at the end of tDLH?
hyperosmotic
4
New cards
What part of the loop of henle is responsible for reabsorption of NaCl?
tALH and TAL
5
New cards
How is NaCl reabsorbed in the tALH?
passively diffuses out
6
New cards
How is NaCL reabsorbed in the TAL?
Actively transported out by Na/K/2Cl
7
New cards
What is the Vte of the TAL?
Positive
8
New cards
Why does the TAL have a positive Vte?
An abundance of apical K channels
9
New cards
What stimulates paracellular cation movement?

10
New cards
How is Na reabsorbed in the TAL?
transcellular and paracellular routes
11
New cards
How is Cl reabsorbed in the TAL?
Transcellular route
12
New cards
What inhibits the Na/K/2Cl cotransporter?
Loop diuretics
13
New cards
How is potassium and calcium reabsorbed in TAL?

16
New cards
How is magnesium reabsorbed by TAL?
Paracellular diffusion
17
