Can I borrow a heart valve from you?

This is actually a heart valve, which we engineered.

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

If you're making an airplane autopilot or an artificial heart pump.

So this valve is called the Tricuspid valve.

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

Civil Horizontal Valve

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.

Anesthetize you, open your chest, put you on an artificial heart and lung machine, drop your body temperature to about 18 centigrade, stop your heart, cut the aorta out, replace it with a plastic valve and a plastic aorta.

Just pull the valve!

Okay. Uh, valve release.

Turbine release valve, activated.

Turn of that valve.

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

It's artificial?

Artificial lifeforms.

Artificial intelligence.

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

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

We need a pressure valve.

Unfortunately, Trevor passed away from a heart attack... while masturbating... to produce sperm for artificial insemination.

Greek'technetos' for artificial

Artificial gravity off.

Engage artificial gravity.

They are artificial.

These are artificial?

An artificial intelligence.

With artificial intelligence, not only have they not created artificial intelligence, they haven't yet created artificial stupidity.

The main valve is turned off.

Here you've got the aortic valve.

It's the pressure reg valve again.

This valve is a sonic trigger.

Surface compression of valve sensors, Captain.

Main valve on, main switch on.

And this valve and all valves in the heart are basically there to keep blood moving in the right direction.

And the fact that pig heart valves have lots of these on them is the reason that you can't transplant a pig heart valve into a person easily.

Likewise, if you have the artificial valve option, you're committed to antibiotic therapy whenever you have any intrusive medical treatment, even trips to the dentist require that you take antibiotics, in case you get an internal infection on the valve.

It's an artificial flower.

Those tears are artificial.

Probably an artificial bird.

Advantages of artificial flowers?

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.
