So this valve is called the Tricuspid valve.

Watch yourself. Increase speed, full throttle.

OK, right throttle, 15 per cent.

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

Civil Horizontal Valve

He put his hand on the throttle.

Anesthesia machine multi parameter monitor, operating lights, suction.

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

They don't stick by Velcro or suction or glue.

How about suction? They stick on in a vacuum.

Could you please allow me to.. ..before the suction..

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.

If we let him go, he'll throttle us in our sleep.

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.

It's that little bar there. He put his hand on the throttle.

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.

Well, we stopped, got out, pulled out the throttle and let her roll.

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.

We're going in full throttle. That ought to keep those fighters off our back.

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

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

And on Sunday morning the neighbors leaf blower comes out, and I want to throttle them.

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

And they don't stick by glue, or they don't work like Velcro, or they don't work with suction.

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.

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.

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.

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.
