Voiceover: Imagine you're
in a movie theater.

You're watching a really,
really long movie.

And you've finished your
entire bucket of popcorn.

And to make matters worse,
you're watching a movie

about a whole bunch of
people on a cruise ship

that hit an iceberg and
so, there's a lot of water

now you have to get up
and go to the bathroom.

They're about the size of a
fist and you've got two of them.

So the kidneys receive
blood from the heart.

you have some that goes up to your brain,

in the picture of the kidneys right here,

is that they've got a
little vessel right there

so sure enough, there's
some blood that comes

which is just a collection
of waste products

in your bladder that
sits about right here,

until it's an appropriate
time to go to the bathroom.

And this box is going to
be what the kidneys do.

So I'm going to give
just a really simplistic

And then in other videos, we'll
go dive deeper into detail.

And your arteries hold onto
all the things in your blood.

This can include things
like your nutrients.

And so nutrients can be anything from say,

They can be things like
your proteins or your

as the building blocks,
or things that help

In addition to your
nutrients, you've also got

oxygen hanging out in your arterial blood.

And your arteries also
contain waste products.

So things your body has made
through cellular respiration

and all these other
processes that we undergo

that we don't need anymore,
that we want to get rid of.

And they can include
things like urea and other

toxic compounds that we
don't want to build up.

And at the same time, it can also include

extra electrolytes, like
sodium that we don't need.

Because if we hold onto
a lot of sodium chloride,

which is just salt, we'll end
up having high blood pressure.

blood pressure, as we'll
talk about in other videos.

of your nutrients, they
become waste products.

And so, your kidneys help
to make sure you don't

So this is all the stuff
you've got hanging out

in the artery that's coming
over to your kidney, right here.

And as you might recall, whenever you have

an artery coming into an
organ or a part of your body,

there should be a vein
that takes the blood away

from it that's going to
return it to the heart.

And so the job of the kidneys
then, is to make it so that

the nutrients you had
in your arterial blood

are collected and maintained
when we get to the vein.

So we want to hold on to
our nutrients, right here.

So you'll have the oxygen
go through the kidneys
