Loop of Henle

responsible for

Water reabsorption from collecting duct

Concentrating urine (concentration depends on length)

Lowering water potential

*Interesting fact - The Loop of Henle is longer in animals from arid (dry) regions and short in mammals from wet regions. This is because animals in wet regions need to maximise the amount of water that is reabsorbed because there is less available.

Two regions

Descending limb

Narrow

Thin Walls

Very permeable to water

Ascending Limb

Wide 

Thick walls

Impermeable to water

The counter current multiplier ***

This effect happens when two liquids flow in opposite directions past eachother. When this happens substrate exchange is greater than if they flowed in the same direction because there is a greater difference in water potential (greater osmotic gradient)

Is it bad that

instead of saying 

In the name of the Father, the Son, and the Holy Spirit. Amen

I say

In the name of Raja, Carmen Carrera, and Jujubee. Amen.
