it doesn't get access to
oxygen inside that blood,

so that's essentially how
you get a heart attack.

And remember, in medicine,
we call heart attacks

But what exactly is
happening in your body?

when you're actually
having a heart attack?

And let's actually start
from the beginning here.

to the heart muscle cells
during a heart attack.

that heart muscle cells
are connected in this way,

to make sure that the
heart pumps properly.

So what exactly is
happening in a heart attack?

So let's say we're looking
at this blockage right here.

So it's this piece right
here that we're representing.

So you've got this plaque
in your artery upstream,

and it's not ruptured,
it's just sitting there.

It's not really doing too much right now.

But then let's say you start
playing soccer, all right?

So you start running around,
chasing after the ball,

blood is being forced to sort
of flow faster and faster

that rushing blood will
sort of bombard your plaque,

So let's say it does rupture in this case,

So you develop this big clot
on that ruptured plaque.

It's not going to get
that much blood, right,

because this thrombus is
blocking off the blood flow.

were getting lots of
oxygen out of that blood,

now, because of that huge
clot that's in the way,

So now all of a sudden
these heart muscle cells

aren't really getting all
the oxygen they need, right?

So now they start to
become oxygen-starved.

They start to get really
hungry for oxygen.

And when they get really
hungry for oxygen,

they start to send pain
signals to the brain.

And these pain signals are
basically telling the brain,

"Brain, we've got like
no oxygen down here.

"You need to do something about this now."

because you're not really
used to pain like this,

and thinks it's maybe an indigestion pain.

just below your heart,
right above your stomach.

So this is actually the
start of a heart attack.
