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.

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.

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

Let me start by orienting you to the heart.

The whole immune system swarms into the lungs.

I cleaned out your laboratory.

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 finally kind of tricky one, but the lungs.

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 heart is actually sitting between the two

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

So what happens is that in a way you have a much bigger lung, but it branches and branches down to distances about the same for a whale, for a man and for a little rodent.

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.

The job, the second job of the heart, is actually also in this picture, and it's called pulmonary flow.

So blood is headed towards the lungs, going first through the trunk, and of course after the trunk, there is left and right I write that up here pulmonary arteries are next.

Smoking has affected his lungs.

He is afraid of getting lung cancer.

Well, Captain Hargis won't be aboard this time.

Here you have our tricuspid valve. And I'm gonna label it just as 'T'

He was operated on for lung cancer.

There is a connection between smoking and lung cancer.

My uncle died of lung cancer.

So there's this actual extra little step here, where blood is going to and from the lungs, and that's the pulmonary flow.

He said, Look, there's a guy down here.

Here's a typical one in its critical stage

They have an increased risk of infection, an increased risk of malignancy.

Marie Budev.

Thank you, Sir.

The coroner's report shows Mulwray had salt water in his lungs.

I think I'm getting the black lung, Pop.

It may cause lung cancer, too.

Well, it's just my luck.

Now look at that. That's a real lung.

Anatomists were arguing very much about that.

What if that gas can't get out?
