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

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

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.

Or 11x over 2, either way.

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.

If you input a 2, well, 2 gets mapped to 2 either way, so that makes sense.

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

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

One way? A round trip's only 2 more.

There is one way to roll a 2.

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

Either way you take the absolute value of a positive 2 or a negative 2, you're going to get a 2.

A is equal to 1, 2 I'll write this way 1, 2, negative 7, 9, 11.

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

If c is 2, let me do it this way.

No way. man 2 Then what day do you think it is? man The 25th. man 2

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

Coming up the other way, 2 doubled plus 1 is 5.

One way, you're thinking of taking 4 5 of 2 3.

Well, it's 2 2 2 2 2 gnus.

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?

Another way you could think about it is 4, if you do a prime factorization, is 2 times 2.

So the y's go between 2 and 2, the x's go from 1 25 all the way to 25

One way to think about this is 2 3 times 4 5 is 4 5 of this 2 3.

Or another way of writing that is 2 to the third power.

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.

Or another way of saying it, it has to be 5 times 2 times 2 times 2, which is the same thing as 5 times 8.

Well 5 2 is the same thing as 2 2 2 2 2.

And the answer is 2.12 in approximation. The way we get this is applying this formula here 2 5 2.

Oh, sorry, what if I multiply both sides by 1 2 or another way is dividing both sides by 2.

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