And remember I call them arteries, because they're going away from the heart. And there are two arteries, so pulmonary arteries left and right pulmonary arteries.

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.

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.

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

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.

He's six foot four. He's 160 pounds.

Lung cancer?

It used to be very time consuming, but now it's nothing.

I cleaned out your laboratory.

And possibly your lungs.

These are the lungs.

Start CPR.

Let me start by orienting you to the heart.

The whole immune system swarms into the lungs.

And so when I draw these two, I really wnat you to just think of the two sides, veins coming from both sides.

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

It seems that cancer is a direct result to injury.

And actually here I'm gonna make the point that there aren't just two pulmonary veins, one for each lung.

And finally kind of tricky one, but the lungs.

Lung cancer. Inoperable.

The bullet went through his lung.

He's got lung cancer.

Now a lung is something very strange.

And I hesitated there just to make sure I got that because it's taking blood away from the heart.

Don't you worry about cholesterol, lung cancer, love handles?

The cold air in his lungs.

Maybe pneumonia once or twice.

Nonsmall cell adenocarcinoma.

It's supposed to be good for your lungs.

I drained his lungs.

Walt has lung cancer.

No breath sounds on the right side, and the belly is rigid.

The heart is actually sitting between the two

So this is a woman, 46 years old, who had recurrent lung cancer.

He died of lung cancer.

Some 17 years ago, I became allergic to Delhi's air.

And it's going to want to get rid of that carbon dioxide.

(Applause) Thank you.

Mulwray had salt water in his lungs.
