So this valve is called the Tricuspid valve.

Reversing the words is genius !

And it passed through the valve here. So this valve is called the Mitral valve.

Civil Horizontal Valve

That's reversing the logical order of things.

One will be the tricuspid valve and the other the mitral valve.

But before it goes it has to passed another valve. So this is a valve right here. Call it Pulmonary valve.

The main valve is turned off.

Here you've got the aortic valve.

This is called a cycle valve tube.

Up here you have the pulmonary valve.

And then the final valve, I need to find a nice spot to write it maybe to right here, this final valve that passes through is called the Aortic valve.

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

Can I borrow a heart valve from you?

And this is how you make a valve.

It's gonna go back perhaps through the mitral valve, it can go there, or it might go through the tricuspid valve.

This is actually a heart valve, which we engineered.

And they get flummoxed in the first few lectures because they keep reversing these.

But how about reversing its role and having the digital information reach us instead?

I welded the breech, but the valve is still gaping.

Does the color of the valve matter? What matters here?

Our strategy for doing that is going to be basically reversing all of the edges.

Let's watch. (Sound of air escaping from valve) (Music) (Whirring sound)

Open the air inlet valve to supply compressed air to the machine

And the way you engineer this heart valve is the same strategy.

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

It's not rebuilding Europe, it's reversing the divergence for the bottom billion, so that they actually catch up.

Because I think it says something about reversing our perception of what we think the good life is.

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

I've drawn the pulmonary valve as being open, but is that really the case?

On the starboard side, there's a big valve! Can you crank that boat down?

This is actually a heart valve that we've engineered, and you can see here, we have the structure of the heart valve and we've seeded that with cells, and then we exercise it.

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

So I cannot tell a happy story about these social trends, and they don't show any signs of reversing themselves.

Now it's reversing that equation, and actually sequestering half a ton of CO2 thanks to the recipe from the coral.

The un digestive food reaches the Ileo cecal valve and enters the large intestine or colon.

You'll hear S1 when the tricuspid and the mitral valve snap shut. So far so good.

For reversing disease, that's what it takes, but if you're just trying to be healthy, you have a spectrum of choices.

And they are like the fundibulator valve of the architectural, uh, what do you think doctor Joseph?

This is the second chamber of the heart. And it gets there by passing through the valve.

At the back of the Machine, open the Air Inlet Valve to supply compressed air to the Machine

On the other side you have the mitral valve, which separates the left atrium from the left ventricle.

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

So these chordae tendinae, these cords are important for that reason. They keep the valve from flipping backwards.

Also denied and eliminated from any further discussion are disc brakes, fuel injection, hydraulic valve lifters, seat belts...
