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

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.

No.

Coronary vessels So, coronary artery and vein.

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.

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

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.

Midway up her right thigh?

And down here the inferior vena cava.

We'll take the case of Rheumatoid Arthritis

The bullet's dug in just over your femoral 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.

You can see two of the leaflets of the aortic valve working there.

Artery up here, artery over here, and then vein in the other two spots.

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.

His vitals are spiking.

A nother inch. it would hit my tibial artery.

And there were a few.

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

And it's job is of course to make sure the blood does not go from the left ventricle back to the left atrium by accident. Wants to make sure there is forward flows.

Single cut to the femoral artery.

I will cite a number of examples to illustrate what I have in mind.

Up into the ascending aorta.

We started by organizing image acquisition from magnetic resonance and CT imaging machines, from which to make a model of the patient's 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.

It doesn't have any veins.

I have allergic rhinitis.

I have chronic rhinitis.

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

I ended up with blunt chest trauma.

I'll write that right here.

Remove the ties that bind...

In the middle, you can see that little structure squeezing out, that's the left ventricle, pushing blood out through the aortic valve.

Just a moment, Jethro. Is the needle in his femoral artery, Mr. Palmer?

Dean, how bad is it?

So when you have dub, you have noise coming from the pulmonic and the aortic valve snapping shut.

There is actually a little spot right there that they drain in to.

Smelling salts.

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

Even just in the last few years, patients with diseases like rheumatoid arthritis and multiple sclerosis and inflammatory bowel disease have a whole new set of therapeutic options that are directed at this re education process.

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'm going to do some surgery here.

OF A WHALE. (A SMALL SlZED ONE.)

And this is of course the aorta. This is my aorta.

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