This is called a cycle valve tube.

And this is how you make a valve.

This is actually a heart valve, which we engineered.

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

Now that's a left ventricle pushing blood up through the aortic valve you can see two of the leaflets of the aortic valve working there up into the ascending aorta.

The Space Shuttle Main Engine program has also been pursuing performance enhancing changes in engine operation for Block II part of the overall Shuttle performance enhancement program to support Space Station objectives.

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

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 trilobal shape at the bottom, which contains the aortic valve.

There's a train station in Japan where the station master is a cat.

China removed and cleaned up the old power station at Great Wall Station.

Even trips to the dentist require that you take antibiotics, in case you get an internal infection on the valve.

People bring their own cooker, he attaches a valve and a steam pipe, and now he gives you espresso coffee.

Block II contains the Block I improvements and adds the alternate high pressure fuel turbopump and the large throat main combustion chamber.

F. Space station

We take the scaffold, we seed it with cells, and you can now see here, the valve leaflets opening and closing.

Its unique cool flow valve can efficiently discharge hot and damp exhaled breath from inside the respirator, allowing easier breathing for users.

Likewise, if you have the artificial valve option, you're committed to antibiotic therapy whenever you have any intrusive medical treatment at all.

In this case, we've grown a corner block.
