Now this is something amazing that your body can do.
Take a look at that picture.
In the first one on the left, you see how we've got
pretty clear blood flow, but then look what's happening
well you already know that process
and detail, right, we've had a damage,
then we had responders, they
infiltrated the wall, it got trapped in there
then it turned into that really tough and fibrous plaque.
But that means those arteries that's really narrowed
in that area look you've got a buildup on both sides.
So what the body can do, if it happens slowly enough,
the body has a plan and you call it collateral circulation
So look at the first drawing,
everything's clear, no problem.
Look at the second drawing, ooh
we have that build up on both sides
but look at the difference in the
vessels that are outside of that main one.
Look at the difference between the
first picture and the second picture.
Looks they're longer, they're reaching for each
other kinda like a plant does towards sunshine.
That's what collateral circulation will do.
So by the time we get to see, if all the time it
works out just right, you see that we've got a blockage
but it's not a problem because we have the
collateral circulation that's now reestablished blood flow
around the blockage.
See what happens in a hurry, a surgeon can
go in and actually do a coronary artery bypass
and that's what they would do is they would
take a piece of vessel from somewhere else
and they will connect it before
the blockage and after the blockage.
But if you give your body enough time, it does it itself.
I mean I know you're in nursing school and there's a
lot of stress but sometimes you just have to sit back
and think about, that is so cool
that your body can respond to that.
So it can create its own collateral circulation,
no surgery required but what is required is time.
A period of time, we need slow- building plaque, this
doesn't just happen if I automatically have a clot block off
and I have complete blockage - this is not
going to be enough or quick enough to respond
but collateral circulation needs time and the
body can come up with on its own backup plan.
