Brittney the Kidney
 
Brittney the Kidney
is quite cute. 
She live in a body  
that just had 2

extra large cokes
as she watched the previews
they show before movies
so nobody moves.

Brittney got ready.
She saw that refill
and knew that liquid
was on its way still.

Sydney has a job.
There's never stagnation.
She does readsorption
and lots of filtration. 
 
She filters the blood
removing the waste
and readsorbes
excess water with haste.

​Our kidneys function
in homeostasis.
Prevention of osmotic
pressure's the basis.

Brittney the Kidney's
in a human being.
The kidneys are shaped
like a kidney bean.
 
Brittney the kidney
is so specialized
with specialized structures,
you could surmise. 

The functional unit
inside of the kidney
is called the nephron
and its work is plenty.

The nephron begins its
work as a filter
and filters the blood
so you don’t go off kilter.

Now part of the nephron
that we must discuss,
is a round sort of structure
called the glomerulus.

Once the blood enters
inside the nephron,
it enters the glo-
merulus before long.

The glomerulus
has many capillaries.
with super thin walls
Through which solute leaves.
​
What is left behind
is the filtered blood
that travels through
and around up above.

The filtrate goes through 
the capillary network
inside of the glomerulus
that does much of the work.

Lucky for us, Glomeruli
don't take vacation
from their tough job of
glomerular filtration.

The filtration process, though,
 does not stop here.
The filtered blood's
called filtrate, my dear. 

Next, is a winding
pathway made of tubes
through which all of the
body's filtrate now moves.

These tubes have a name. 
The renal tubules. See? 
It's made up of 3 segments
 One, two and three.

The first one of these
is called the proximal
tubule with structure that
makes its function optimal

for a process called
tubular filtration.
The process is solute and
liquid separation

Next I'll explain the second
part of the 3.
This section of tubule is the
Loop of Henle.

This loop travels downward
and then it bends
and makes a U-turn
and then it ascends. 

The third part of tubule
bends and it winds
back and then forth for
a couple of times.

The filtrate travels this
obstacle course. 
that they call the distal
tubule, of course. 

The next part to come
is the collecting duct.
If readsorption's not through
well then you're really..... unfortunate.

At this point, the filtrate
has all become urine
from the readsoption
that we saw occurin'.

From the collecting duct
into the ureter,
 a sudden urge came
as she sat in the theater.

Then on from there the pee
enters the bladder.
Her friend looked at her 
and said, "What is the matter?"

Off to the restroom
the body then flew. 
This story of Brittney the
Kidney's now through.

Next time you drink
be rather thankful.
And maybe do one 
coke instead of a tank-full. 

 
The acronym A WET BED
Will help all its function to stick in your head
 
The A is for acid, as in pH balance
To protect from imbalance of pH is the challenge.
If you are too basic you get alkalosis
If you are too acidic you get acidosis.
 
The W is for the balance of water
If you get dehydrated that would be a bother.
 
Equally important are your electrolytes
If you guessed that was what E was for,
you would be right!
 
These are the ions like potassium
And sodium and magnesium
 
They help you to function
When every one
Of them is in balance
your body can run.
 
The T in the acronym stands for removal
Of toxins from your blood stream. It has my approval!
 
if things get too toxic you become sick.
With too much toxicity your kidneys will quit.
 
The B is for the blood-pressure control.
Did you think what I said before was the whole?
 
The kidneys even exert their power
By excreting hormones for blood-pressure power.
 
You might be wondering how they perform this function too.
They perform this function through angiotensin II.
 
This is a hormones that causes restriction
Of the blood vessels to cause a prediction
 
Of raising the blood pressure of their own host.
Like when you sit up, when you need it the most.
 
There is another product that is important
Erythropoietin keeps blood cells in proportion
 
D is the last letter in our cute acronym.
It stands for the “D” in your daily vitamin.
 
Too much of this vitamin can become a toxin.
These kidney shield us by keeping it boxed in.
 
The function of kidneys fall in the groups
Secretion of hormones
 
If you will be patient I would like to start with this
The process we call gluconeogenesis
 
When you try to diet it is increased
To readsorb glucose from the kidneys.
 
When someone you know does not have this
They could get dibetes mille
