Keith Bellows Yeah, yeah.

And so we've just added this manual bellows.

This is called a cycle valve tube.

And this is how you make a valve.

But instead of a bellows, I had a leaf blower.

This is actually a heart valve, which we engineered.

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

Hello. This is Keith Bellows with the National Geographic Camel Investigation Unit.

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.

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.

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.

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

The bellows are burned, the lead is consumed of the fire the founder melteth in vain for the wicked are not plucked away.

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.

So, the most beautiful thing I found at least what I think is the most beautiful in the book, is this heart valve.

So this is actually a Dutch company, so I called them up, and I asked, Can I borrow a heart valve from you?

Great and then I didn't hear from them for weeks, so I called, and I asked, What's going on with the heart valve?

The bellows blow fiercely the lead is consumed of the fire in vain do they go on refining for the wicked are not plucked away.

He turned the wrong valve when he filled his cylinder he had 80 percent oxygen in his tank when he should have had 40.

The low tech bit is that it's literally a pig's heart valve mounted in the high tech bit, which is a memory metal casing.

So you see the leaflets opening and closing of this heart valve that's currently being used experimentally to try to get it to further studies.

The fire disaster happened at about 10 00am and was put out at about 10 30am. It is the snifting valve inside that triggered the fire.

And they said, Well the director of the company decided not to let you borrow this heart valve, because want his product to be associated with pigs.

And some of these models so you take a bit of this cycle valve tube, you can put two matchsticks inside this, and you make a flexible joint.

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.

And once it's in the right spot, they remove the outer shell, and the heart valve, well, it gets this shape and at that moment it starts beating, instantly.

Bring me blocks of iron to fill up the passage between the two mountains. He told them to ply their bellows until the iron became hot as fire. Then he told them to pour on it molten brass.

Bring me sheets of iron until, when he had leveled them between the two mountain walls, he said, Blow with bellows , until when he had made it like fire, he said, Bring me, that I may pour over it molten copper.

But many other single currency areas, including the US, display similar divergence. It should also be obvious that, in the absence of currency markets to act as a valve for economic and financial pressures, economic volatility may increase.

Bring me ingots of iron, (which they did) until the space between two mountain sides was filled up. Blow your bellows, he said (and they blew) until it was red hot. Bring me molten brass, he said, that I may pour over it.

Keith Bellows gleefully outlines the engineering marvels of the camel, a vital creature he calls the SUV of the desert. Though he couldn't bring a live camel to TED, he gets his camera crew as close as humanly possible to a one ton beast in full rut.

Bring me ingots of iron. Then after he had filled up the space between the two mountain sides, he said (Light a fire) and ply bellows. When he had made it (red like) fire, he said Bring me molten copper which I may pour on it.
