Video Transcript
I'm engineers in this video we're going
to talk about the mechanics of breathing
so it's going to be a tough topic for
certain people to understand especially
with the pressures so we're going to do
our best here and engineered science to
make sense of that so it's going to dig
right in so before we do that we need to
look at a little bit of anatomy for the
lungs and a lot of the chest wall
structure so let's do that first
so if you look here we have two lungs
right right left lung and what's going
to happen is you're going to have you
know the actual trachea the trach is
going to branch off into the right and
left primary bronchus serving the actual
lung specifically at the smallest
structural unit called the alveoli we'll
talk about that in a second but the lung
itself each individual allo lives making
up the lung but if you look at the lung
it has this nice little thin epithelial
tissue with a little bit of areolar
connective tissue clinging on to that
organ so you just blue layer right there
that blue layer right there we're going
to denote this layer right here let's
call this layer 1 ok so layer 1 right
there so layer 1 is specifically called
the actual visceral pleura so again this
layer 1 is actually called the visceral
pleura okay that's the first layer then
let's keep working our way out now you
see this space right here this little
hollow like cavity but it has a little
bit of fluid in it
this space right here we're going to
call this number 2 here so number 2
number 2 is actually this whole cavity
here is actually specifically called the
pleural cavity now here's what's
interesting about the pleural cavity in
this diagram I'm actually showing a
space in the human body there actually
is no space it's actually a potential
space they call it and the reason why is
in our human body the lungs this
visceral pleura is tethered or connected
to the actual this pleura right here
