CPR.

Start CPR.

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

I see. Cease CPR.

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

Oh, you got lucky.

Blood flows from the right atrium to the right ventricle, then it goes to the lungs and from the left atrium to the left ventricle.

The heart is actually sitting between the two

Shall we practice the practical skill portion?

I don't feel a pulse, doctor. Charge vfib?

The diaphragm becomes the floor, and the ribs are kind of the ceiling and the walls of this space.

Your lungs stop breathing, your heart stops pumping.

This is the right lung and on this side you'd have the left lung. So this is where your heart sits between two lungs.

This is chamber number two. It goes to the lungs and then back up to the left atrium.

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.

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.

So we've gone from the right ventricle around to the lungs, back again into the left atrium.

And then it's gonna come out on the other side, in the pulmonary veins.

Oh, the second goes higher on the chest. Aim for the heart and 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.

Every single second that you are not sitting still, you are actively improving the health of your heart, and your lungs and brains.

But now remember that blood is constantly moving through the heart, so in a previous cycle you actually had some blood that's coming back from the lungs and that's what's dumping into the left ventricle.

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

Lung cancer?

Her blood pressure was an alarming 230 over 170.

So now you can see that the heart is really two different system err let'say two different circuit, rather.

Well there was a little piece of that Women's Health Initiative that went to National Heart, Lung, and Blood Institute, which is the cardiology part of the NlH.

I cleaned out your laboratory.

And possibly your lungs.

These are the lungs.

Let's start by labeling our heart, at the top, blood is coming into the right atrium, going to the right ventricle, it goes off to the lungs, comes back into the left atrium and then the left ventricle.

Let me start by orienting you to the heart.

The whole immune system swarms into the lungs.

And It's again stopped a little bit there, but I can fill it in and the pulmonary veins are gonna deliver that oxygenated blood to the left atrium.

Angle of the trajectory indicates the bullet traveled through the first intercostal space avoiding the heart and bronchial branch of the lungs.

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.
