His vitals are spiking.

And then, when the heart is ready to pump it back out, it goes into this artery, and the name of it is the aorta.

And let me actually show you where the blood vessels come from. These are called coronary vessels I just write the word coronary here.

Now, to start the journey, it's gonna have to out of the left ventricle and into the largest artery of the body.

It doesn't have any veins.

Coronary vessels So, coronary artery and vein.

And the veins actually drain into a spot , directly into the right atrium.

And on the right you actually see a carotid artery that was engineered.

Remove the ties that bind...

I'm going to do some surgery here.

Right it's gonna have to go away from the heart. So that's the aorta. The aorta actually has the little arch like that.

I could just write artery and vein and essentially they would be behaving this way.

Smelling salts.

If the artery gets nicked, how long do i have?

I think she cut both arteries. I could hardly feel her pulse.

So these two veins, the superior vena cava and the inferior vena cava, are dragging the blood back to the heart, and, generally speaking, these are all considered, of course, veins.

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.

She's hardly breathing. Better call it in.

And you might say, well that wasn't so difficult. I'll say bronchial vessels, because there are also some veins coming off.

But, actually lungs are kind of interesting in the sense that there is a lot of mixing going on.

He's dying. Coronary blockage.

Remember the heart itself is a muscle. It itself needs oxygen.

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

No lesions. No aneurysms.

MAP's at 55.

In the jugular preferably. okay.

In your jugular on the side of your neck.

Midway up her right thigh?

So what happens when a person gets a retinal degenerative disease like macular degeneration?

A pulse.

Let's say this one goes towards my foot, and this is going to be now an even smaller artery.

What's happening between these two, time like here, is that blood is actually squeezing out because the pulmonic and aortic valves just opened, blood is squeezing out and going to the whole body.

So let's start up on the left side.

The risk of permanent damage Seizures, aneurysms, memory loss, death...

Start the drip. Okay. I can't find a vein.

The aneurysm has been repaired.

Well, these vessels, all of them, together are called coronary vessels.

And as I say, most of them really die very horribly, 80 is very bad for you. now that means, that is really bizarre that one should ask the question why should we defy aging.

They're taking the de oxygenated blood away from the tissue of the heart.

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

And down here the inferior vena cava.

Had some kind of a brain aneurysm.

Stay clear of the hepatic artery.

I know about the aneurysm, Chad.

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.
