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.

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.

Midway up her right thigh?

And down here the inferior vena cava.

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.

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.

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.

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.

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?

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?

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.

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.

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

You can see how the pulmonary and aortic valve are closed when the mitral and tricuspid valve are open.

It has a funny tri lobal shape at the bottom, which contains the aortic valve.
