Loop of Henle

What type of fluid is the loop of henle responsible for producing?

Hypo or hyperosmotic fluid depending on the water needs of the body

What is reabsorbed in the thing descending loop?

Water

Is the water hypo or hyperosmotic at the end of tDLH?

hyperosmotic

What part of the loop of henle is responsible for reabsorption of NaCl?

tALH and TAL

How is NaCl reabsorbed in the tALH?

passively diffuses out

How is NaCL reabsorbed in the TAL?

Actively transported out by Na/K/2Cl

What is the Vte of the TAL?

Positive

Why does the TAL have a positive Vte?

An abundance of apical K channels

What stimulates paracellular cation movement?

Positive Vte

How is Na reabsorbed in the TAL?

transcellular and paracellular routes

How is Cl reabsorbed in the TAL?

Transcellular route

What inhibits the Na/K/2Cl cotransporter?

Loop diuretics

How is potassium and calcium reabsorbed in TAL?

Half paracellular half transcellular

What inhibits reabsorption of calcium?

Loop diuretics (c)

What percent of magnesium is reabsorbed by TAL?

70%

How is magnesium reabsorbed by TAL?

Paracellular diffusion

How is mg reabsorption inhibited?

Loop diuretics and activation of a Ca sensing receptor
