I'll show you an example of that real quickly.

He's dying. Coronary blockage.

I want to clarify some of the terminology I used in the last video.

I wouldn't have been able to do anything

Here's a classic example

And this right over here in red is called the right coronary arteries or the RCA.

I can't imagine what that would bring.

This pig at 10 06 was having a heart attack.

Children nowaday have very limited space for healthy activites.

So what happens is that the heart, before sending blood out the aorta, before just dishing it out back into the body, it actually sends the blood over to the lungs.

This is fortress of Allah!

Well, what is needed for the earliest possible warning of a heart attack?

Well, he kept the balloon filled to block the artery, to simulate a blockage, which is what a heart attack is.

And if you look carefully, you can see that there's a black blush right there.

He too, however, occupies an equally narrow house at present.

Shore up the door!

We're cut off.

And actually it stop there because of my arrows, but you can actually see now deoxygenated blood kind of goes from the right ventricle, through the pulmonary trunk, through the arteries and into the left and right lung.

I've got lung cancer.

Lung cancer.

Oh, that's a rough one.

Me, is greater.

What is this, Gordon, your fortress?

Let me start by orienting you to the heart.

Guard of the Citadel.

Slurping

And it gives you the clue where the things we are going to go next. Because the word pulmonary means lungs.

Now suppose you live in a certain part of a certain remote place and you have a loved one who has blockages in two coronary arteries and your family doctor refers that loved one to a cardiologist who's batting 200 on angioplasties.

We got water out of him.

Lungs? No.

And the husband with the lung cancer who disappears for hours, and I don't know where he goes.

CPR.

The bullet went through his lung.

The whole immune system swarms into the lungs.

Walt has lung cancer.

This is what we call a plaque.

We're sunk.

We're up against the wall.

Follow me to the barricade.

what the hell was that? barricade the door!

Ahh...

This is a heart stent developed by Zhong You at Oxford University.

One of the reasons that I took my year off was to spend more time with my family, and this really tragic thing happened where my sister in law, her intestine suddenly strangled one day, and we took her to the emergency room, and she was, she was in really bad shape.

But this is not as I said in the beginning bad way of thinking about it.
