I have pyorrhea.

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

I'm worried because the dentist I went to recently told me, You've got periodontitis alright .

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

His vitals are spiking.

Coronary vessels So, coronary artery and vein.

Remove the ties that bind...

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.

In the jugular preferably. okay.

Smelling salts.

This guy didn't have a chance. He's got rods going through every major artery in his body. Your life is in her hands.

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 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.

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

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

It doesn't have any veins.

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

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

Pretty soon, the dentist'll have to clean the tank... and when he does, he'll take us out of the tank... put us in individual baggies... then we'll roll ourselves down the counter... out the window, off the awning... into the bushes, across the street... and into the harbor!

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

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

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.

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

Had some kind of a brain aneurysm.

I know about the aneurysm, Chad.

I'm going to do some surgery here.

Everyone, into the tub, quickly!

Water tank leak.

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

Suddenly, I had an episode of catastrophic bleeding.

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 your jugular on the side of your neck.

Midway up her right thigh?

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

Or from the point of view of the person whose heart it is, it's on the left.

This vessel I'm gonna label let's say here, as the Aorta.

Now, these are very, very tiny branches coming off of my small artery, and let's follow this one right here, and this one is my arteriole.

A nother inch. it would hit my tibial 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.
