He's Dr Chris.

0:00:230:00:24

And he's Dr Xand.

0:00:250:00:28

And yes, we're twins.

0:00:280:00:29

Do you know how brilliant your body really is?

0:00:310:00:33

My finger's got yellow puss in it.

0:00:330:00:36

Well, we're going to show you.

0:00:360:00:38

Yeah.

0:00:380:00:39

'In this series, we're pushing our bodies to their limits...'

0:00:390:00:42

I like the sound of this.

0:00:420:00:43

'..by doing extraordinary experiments on each other.'

0:00:430:00:46

This is my sick.

0:00:460:00:48

'To uncover what goes on inside.'

0:00:480:00:50

Ooh, that just came out of my ear.

0:00:500:00:53

'And out.'

0:00:530:00:54

Wow, that's amazing.

0:00:540:00:55

From the bizarre.

0:00:550:00:57

To the incredible.

0:00:580:00:59

So now I'm seeing things.

0:00:590:01:01

'It's time to find out what you're made of.'

0:01:010:01:03

Chris?

0:01:030:01:04

Chris?

0:01:040:01:06

Chris?

0:01:060:01:07

Coming up today...

0:01:090:01:10

On Operation Ouch!

0:01:100:01:11

Things get gooey as we explore earwax.

0:01:140:01:16

Oh that's amazing, that's great.

0:01:180:01:20

Ooh, I've been stung.

0:01:200:01:22

Find out what to do if this happens to you.

0:01:220:01:25

And Xand is wowed by artificial organs.

0:01:260:01:30

I wonder who's going to end up with this?

0:01:300:01:33

But first...

0:01:330:01:34

Medical teams always expect the unexpected...

0:01:350:01:38

But no-one was expecting this.

0:01:380:01:40

In the waiting room is nine-year-old Lauren with her family and

0:01:450:01:49

she's bitten off more than she can chew.

0:01:490:01:51

I swallowed a clip.

0:01:510:01:53

A what?

0:01:530:01:55

It was a hair clip.

0:01:550:01:56

Mm-hmm.

0:01:560:01:57

And I took it out my hair...

0:01:570:01:59

Mm-hmm.

0:01:590:02:00

..to get my hair to get my hair flat and then I swallowed it and I...

0:02:000:02:02

Hmm, hang on.

0:02:020:02:04

Let's get this story straight.

0:02:040:02:05

Lauren was at home sitting on the sofa, watching TV with her granddad.

0:02:080:02:12

I don't think he's watching the programme,

0:02:120:02:14

someone else isn't watching the show either.

0:02:140:02:18

Hmm. Anyway, whilst Lauren was watching the telly,

0:02:180:02:21

she took her hair clip out of her hair as you do.

0:02:210:02:24

Yep, but what she's about to do isn't the best of ideas.

0:02:250:02:29

I know. She likes chewing clips and she was busy playing with this one

0:02:290:02:32

in her mouth when all of a sudden she accidentally swallowed it

0:02:320:02:36

and it's never been seen since.

0:02:360:02:38

Oh, dear, ouch.

0:02:380:02:40

What does Granddad have to say about all this?

0:02:410:02:44

She suddenly jumped up and ran out cos her gran was in the kitchen.

0:02:440:02:48

I was still reading the paper, so I didn't even know what had happened.

0:02:480:02:52

A lot of help you were, Granddad.

0:02:520:02:54

But at least someone's taking it seriously.

0:02:540:02:57

She put clips in her mouth, what's very naughty and bad.

0:02:570:03:02

You got it.

0:03:020:03:03

Anyway, with this clip lurking somewhere inside you, Lauren,

0:03:030:03:06

we need to get you checked out pronto.

0:03:060:03:08

And here's the man for the job.

0:03:110:03:13

Over to Dr Tom Cibulskas.

0:03:130:03:15

And how big was it, can you show me?

0:03:150:03:17

-Well, I think it was that big, like that.

-OK.

0:03:170:03:20

-Well, the hair clips are about that big, aren't they?

-Oh, OK.

0:03:200:03:23

Probably a couple of inches you think? So quite big actually.

0:03:230:03:26

OK.

0:03:260:03:27

I'm glad we sorted that out.

0:03:270:03:29

And if you swallow, does it feel uncomfortable?

0:03:290:03:32

-Yeah.

-It does.

0:03:320:03:33

And what we need to work out is

0:03:330:03:35

whether or not the hair clip is stuck in her throat

0:03:350:03:37

or whether it's actually gone down into her stomach.

0:03:370:03:41

When you swallow something, it goes down your throat

0:03:410:03:44

into your oesophagus, or food pipe,

0:03:440:03:46

and then into your stomach.

0:03:460:03:49

Lauren's hairclip might already have done this journey.

0:03:490:03:52

But if it's still in her throat,

0:03:530:03:55

it could go down her trachea, or windpipe,

0:03:550:03:58

and end up in her lungs.

0:03:580:04:00

Which would cause her to choke.

0:04:000:04:02

Did it feel like it went all the way down when you swallowed it?

0:04:030:04:06

-No, I didn't feel like it all went down.

-Doesn't feel like that.

0:04:060:04:10

OK, now I'm just going to pop this on your tongue.

0:04:100:04:12

-Just say ah.

-Ah.

0:04:120:04:13

OK, I can't see anything there at all.

0:04:130:04:16

Well, apart from her tongue and teeth obviously.

0:04:160:04:18

But to try to find out where on earth that clip has got to,

0:04:180:04:21

Dr Tom has what might seem like a harebrained idea.

0:04:210:04:25

OK, Lauren, we've got this little gadget, it's a metal detector.

0:04:250:04:28

It'll help us work out which part of you we need to X-ray

0:04:280:04:30

to find where the hairclip's gone.

0:04:300:04:34

-Listen out for the beeps everyone.

-MACHINE BEEPS

0:04:340:04:37

-Bingo.

-Yep, we've got a belly beep.

0:04:370:04:40

But at least we can give her throat the all clear which is good news.

0:04:420:04:45

Sometimes when we swallow things that are a pointy or sharp,

0:04:470:04:49

it can feel like they're stuck.

0:04:490:04:51

But actually what that feeling is,

0:04:510:04:53

is it's where it's scraped or scratched

0:04:530:04:55

the lining of your food pipe

0:04:550:04:56

and actually it may have gone down and it may be in the stomach.

0:04:560:04:59

So her throat's clear, but this investigation isn't over yet.

0:04:590:05:03

Dr Tom needs to find out exactly where the clip is in Lauren's belly,

0:05:030:05:07

to make sure it won't cause a dangerous blockage

0:05:070:05:09

in the narrowest part of her intestines.

0:05:090:05:12

So it's off to X-ray.

0:05:120:05:13

We'll be back later to see how she gets on.

0:05:160:05:19

And now to our lab.

0:05:270:05:29

Where we do incredible experiments.

0:05:290:05:32

Oh, there you go.

0:05:320:05:33

To show you how your body works.

0:05:330:05:35

Just don't try anything you see here at home.

0:05:360:05:39

This is a tiny camera and I'm going to look inside Chris's head with it.

0:05:400:05:46

Now you must never put anything in your ears

0:05:460:05:48

or you could cause permanent damage.

0:05:480:05:50

We can only do this because we're doctors.

0:05:500:05:54

Oh, that's great, that is Chris's eardrum. Lovely.

0:05:540:05:58

OK, Chris, what I want you to do is close your mouth.

0:05:580:06:01

Plug your nose.

0:06:010:06:03

And now blow out gently.

0:06:030:06:05

Oh that's really good, that's lovely.

0:06:060:06:08

So what you can see there is Chris's eardrum bulging.

0:06:080:06:11

Now the eardrum's a very thin membrane which acts like a drum.

0:06:110:06:16

That's why it's called the eardrum.

0:06:160:06:17

It vibrates when sound waves hit it, but it has another important job -

0:06:170:06:21

it protects the very delicate middle and inner ears behind it.

0:06:210:06:25

But there's something else lurking inside your ears

0:06:250:06:28

that we want to show you.

0:06:280:06:29

I tell you what, Xand, give me the camera

0:06:290:06:31

and I'll have a look at your ears.

0:06:310:06:33

Can you see that gooey, yellow, browny, crumbly stuff?

0:06:340:06:39

That is Xand's earwax.

0:06:390:06:41

How much do I have?

0:06:410:06:43

A lot more than me.

0:06:430:06:44

That's great, because earwax is in our ears for a good reason.

0:06:440:06:48

But what is earwax and why do we have it?

0:06:480:06:51

Well, we're going to show you.

0:06:510:06:52

Yep, I can see right through to the other side.

0:06:550:06:58

What, really? Well how many fingers am I holding up then?

0:06:580:07:02

Three.

0:07:030:07:05

Wow. Didn't think that was medically possible.

0:07:050:07:07

Now look, that is a good sample of your earwax.

0:07:070:07:12

It's not pretty to look at, but it is brilliant stuff.

0:07:120:07:15

Earwax is actually a type of sweat.

0:07:150:07:17

Some people get more than others,

0:07:170:07:19

just like some people sweat more than others.

0:07:190:07:21

But everyone has it.

0:07:210:07:23

When the earwax is produced in your ear canal it's runny,

0:07:230:07:26

but it dries out as it works its way out of your ear.

0:07:260:07:29

This takes about a month and it's helped along by you yawning,

0:07:290:07:32

chewing, chatting until it flakes out of your ear naturally.

0:07:320:07:35

So next time you get told off for chatting in class,

0:07:350:07:38

you could always say you're trying to work out your earwax.

0:07:380:07:42

Xand, what are you doing?

0:07:420:07:44

I was just tasting it.

0:07:440:07:45

I can see that, but why?

0:07:450:07:47

I guess I just wanted to know what it tasted like.

0:07:470:07:49

Well, what does it taste like?

0:07:490:07:52

Actually it's not very nice.

0:07:520:07:53

It's very bitter and that's

0:07:530:07:55

because earwax is made up of around 40 different substances.

0:07:550:07:58

The main ones are fatty acids and cholesterol

0:07:580:08:00

and none of them taste very nice.

0:08:000:08:03

Plus the fact that it's been in your ear for about the last month.

0:08:030:08:06

Anyway, now we know what's in earwax, what's it for?

0:08:060:08:10

Well, to show you, I've got a model of Xand's ear.

0:08:100:08:13

There we go, Xand.

0:08:190:08:20

Whoa.

0:08:200:08:21

It's amazing.

0:08:210:08:22

Hello?

0:08:240:08:25

ECHOES

0:08:250:08:26

It even sounds like me.

0:08:260:08:28

Anyway, in the air around us there are lots of particles of dust

0:08:280:08:31

and bugs and other stuff.

0:08:310:08:33

So for this experiment,

0:08:330:08:34

I'm going to need some giant particles

0:08:340:08:36

to go with Xand's giant ear.

0:08:360:08:38

But as we don't have any giant bugs or dirt to go with the giant ear,

0:08:380:08:42

these polystyrene balls will have to do.

0:08:420:08:44

Now when air passes around us,

0:08:440:08:46

some of these dirt or bug particles could get into our ears.

0:08:460:08:50

Watch.

0:08:500:08:51

With everything else supersized,

0:08:530:08:55

we thought we'd go for a supersized gust of wind too.

0:08:550:08:59

Ear goes.

0:08:590:09:00

'See how many went through the hole?'

0:09:060:09:09

If this was a real ear, all the dust and dirt particles that went through

0:09:090:09:12

would have clogged up the eardrum and damaged the inner ear behind it.

0:09:120:09:17

So here's the only problem with this otherwise amazing model,

0:09:170:09:21

it doesn't have any earwax.

0:09:210:09:23

So let's smear an earwax type gunk in there and see what happens.

0:09:230:09:26

We're coating the big ear with a layer of sticky yellow stuff,

0:09:290:09:32

a bit like the wax in your ear and you'll see how it protects

0:09:320:09:35

your delicate eardrum and the inner ear behind it.

0:09:350:09:38

Ready? Here we go again.

0:09:410:09:43

Oh, that's amazing, that's great.

0:09:450:09:47

Look loads of them have stuck in there.

0:09:480:09:51

But that's what happens every day in your ears.

0:09:540:09:57

Any unwanted specks of dirt or bugs that get blown near your ears,

0:09:570:10:01

get stuck in your earwax and then moved out of your ear.

0:10:010:10:05

Which means your eardrum and everything behind it stays safe.

0:10:050:10:09

The other great thing about your earwax is that the acid in it

0:10:090:10:11

deters bacteria too, so it keeps infection out.

0:10:110:10:15

So although it might taste horrible to Xand,

0:10:150:10:18

it also tastes horrible for bugs.

0:10:180:10:20

The park, a place to have fun.

0:10:270:10:29

Wee, wee, wee, wee!

0:10:290:10:32

But it's also a place of danger.

0:10:330:10:36

You could trip up on skipping ropes.

0:10:380:10:41

You can get splatted on the forehead by a large ice cream.

0:10:420:10:45

-Oh, what's the time, Xand?

-I'll check.

0:10:450:10:48

Or you could slip on a banana skin.

0:10:500:10:52

Actually, Chris, I think you're the one

0:10:550:10:56

that's more likely to have an accident because you're so clumsy.

0:10:560:10:59

What? You're the clumsy one.

0:10:590:11:01

BUZZING

0:11:010:11:02

You're more likely to slip on something.

0:11:020:11:04

BUZZING

0:11:040:11:05

You could splat me in the face with your ice cream.

0:11:050:11:08

Eugh.

0:11:080:11:09

Eugh. I've been stung!

0:11:110:11:13

Ooh. A minor injury.

0:11:150:11:17

So...

0:11:230:11:24

..screaming, "I want my teddy!"?

0:11:280:11:30

..and put something cold on the area

0:11:370:11:39

for no more than ten minutes?

0:11:390:11:40

The answer is C.

0:11:450:11:46

So to treat a sting...

0:11:490:11:51

First of all scrape out the sting

0:11:510:11:53

with something like a credit card or your nail.

0:11:530:11:55

The sting sticks out and looks like a splinter.

0:11:560:11:59

Then put something cold on the area like frozen peas.

0:12:030:12:06

-How's that?

-Much better.

0:12:080:12:10

Good. Now hang on just a second.

0:12:100:12:12

I want my teddy bear. I want my teddy bear.

0:12:140:12:17

What are you doing?

0:12:170:12:19

I'm just trying option A.

0:12:190:12:20

But, Xand, you weren't even stung.

0:12:200:12:22

So scrape out the sting and put something cold on it

0:12:250:12:28

for no longer than ten minutes.

0:12:280:12:29

If you're worried, tell an adult.

0:12:290:12:31

We've got some incredible body tricks for you to show your friends.

0:12:350:12:38

Everyone's going to want to try this one.

0:12:390:12:43

We've got a really tasty trick for you

0:12:430:12:45

and I'm going to use Xand as my first volunteer.

0:12:450:12:48

So do you fancy a doughnut?

0:12:480:12:49

Oh, lovely.

0:12:490:12:50

No, no, no...

0:12:500:12:52

It's not how the trick works, you've got to slow down.

0:12:520:12:54

So what we're going to do is we're going to give Xand

0:12:540:12:57

this doughnut which is covered in sugar

0:12:570:12:58

and you've got to eat the whole thing without licking your lips.

0:12:580:13:01

Do you think you can do this?

0:13:010:13:03

Yeah, well, that's easy, I could do that all day.

0:13:030:13:05

OK, ready? Here we go, this is the doughnut.

0:13:050:13:08

'Now let's see if Xand can eat his doughnut without licking his lips.'

0:13:080:13:12

-CHANTING:

-Xand! Xand! Xand!

-It's difficult.

0:13:120:13:14

Xand! Xand! Xand!

0:13:140:13:16

You're doing quite well so far, Xand, but can you keep it up?

0:13:160:13:19

Xand! Xand! Xand!

0:13:190:13:20

'Oh, you've licked.'

0:13:200:13:22

Oh, look.

0:13:220:13:23

Who thinks that they could do the trick well?

0:13:240:13:27

-ALL:

-Me!

0:13:270:13:29

What you think you're better than me?

0:13:290:13:30

-ALL:

-Yeah.

0:13:300:13:31

Well, let's see how this lot get on.

0:13:330:13:35

-They're trying very hard.

-And so far no-one's licked.

0:13:370:13:42

You're going to lick soon, you're going to lick soon.

0:13:420:13:44

Sooner or later, it becomes too much to resist.

0:13:440:13:47

Ah.

0:13:470:13:48

He's licking.

0:13:500:13:51

She's definitely licking.

0:13:530:13:56

And so is he.

0:13:560:13:57

So why's it so hard to resist licking the sugar off your lips?

0:13:580:14:03

When the jam and sugar was on your lips, it was sort of irritating.

0:14:030:14:08

You wanted to get rid of the irritation

0:14:080:14:10

and wanted the tastiness of it.

0:14:100:14:12

Charly has almost got it.

0:14:150:14:17

Your lips have more sensory receptors

0:14:170:14:19

than pretty much anywhere else,

0:14:190:14:21

making them super sensitive to even the smallest bit of sugar.

0:14:210:14:24

So as soon as the receptors feel something touching them,

0:14:260:14:29

they tell your brain to remove the irritation.

0:14:290:14:32

That's why you lick your lips.

0:14:320:14:35

It's not just that you get the tasty treat

0:14:350:14:37

of having all the jam and sugar on your lips,

0:14:370:14:40

but you also...

0:14:400:14:41

-He's eating doughnuts.

-Xand?

0:14:410:14:43

KIDS SCREAM

0:14:430:14:44

What you doing?

0:14:440:14:46

I'm just practising.

0:14:460:14:47

Earlier, Lauren turned up after swallowing a hairclip.

0:14:520:14:55

Let's see how she's getting on in accident and emergency.

0:14:550:14:58

Back at Royal Manchester Children's Hospital,

0:15:010:15:03

Lauren is hoping her swallowed hairclip can be found.

0:15:030:15:07

She'd been watching TV with her granddad,

0:15:070:15:10

who wasn't really watching at all,

0:15:100:15:12

when she decided to chew her hairclip

0:15:120:15:14

and accidentally swallowed it.

0:15:140:15:16

And I'm always telling her not to put clips in her mouth

0:15:160:15:19

but as usual she doesn't listen.

0:15:190:15:20

You must listen to your mum what she just said.

0:15:200:15:25

Tell that to your big sis.

0:15:250:15:27

Luckily the clip hadn't got stuck in Lauren's throat,

0:15:280:15:31

but it could still cause a dangerous blockage

0:15:310:15:33

in the narrowest part of her intestines.

0:15:330:15:37

So now she's in X-ray to find out

0:15:370:15:39

precisely what part of her belly it's hiding in.

0:15:390:15:42

Nice and still for me.

0:15:420:15:44

Anyone see it?

0:15:450:15:46

-Yeah, there it is.

-Oh, no.

0:15:460:15:48

-Yeah.

-I was looking up there, then.

0:15:480:15:51

Oh, hello, hairclip.

0:15:510:15:53

-So is that, that is her stomach, isn't it?

-Yeah.

0:15:530:15:55

And the good news is it's already passed the narrow part

0:15:570:16:00

of her intestines where it could have caused a dangerous blockage.

0:16:000:16:05

We can see it's working its way through your tummy now

0:16:050:16:07

and I'm afraid there's nothing we can do

0:16:070:16:09

apart from wait for it to come out the end.

0:16:090:16:11

And you know what that means.

0:16:110:16:12

You'll have to do-do, a number two-two.

0:16:120:16:15

I think if you make sure when you go to the toilet

0:16:150:16:17

over the next few days,

0:16:170:16:18

if you keep an eye out I think you'll probably see it.

0:16:180:16:21

Is that OK?

0:16:210:16:22

So it's off home for Lauren who'll be on poo patrol

0:16:220:16:25

for the next couple of days.

0:16:250:16:27

Everybody wave.

0:16:270:16:29

CHRIS AND XAND: Bye.

0:16:290:16:30

Still to come in accident and emergency,

0:16:350:16:37

Amy's toe needs attention.

0:16:370:16:39

Find out how your amazing body heals itself.

0:16:410:16:43

And prepare for a medical breakthrough.

0:16:450:16:48

Feels very much like a real ear.

0:16:480:16:49

Now, did you know your spinal cord is as flexible as a garden hose?

0:16:510:16:55

That's amazing and so is this.

0:16:570:16:59

In an ordinary town...

0:17:010:17:03

An ordinary street.

0:17:030:17:05

..people walking about.

0:17:050:17:07

There's nothing amazing about walking, Xand.

0:17:070:17:10

Look closer, Chris.

0:17:100:17:11

Wow, that guy's walking on his hands, brilliant.

0:17:120:17:15

Brilliant, yes. But is it amazing?

0:17:170:17:20

Well, just wait and see, Chris.

0:17:200:17:22

This is Charlie Wheeler and he's got an incredibly bendy body.

0:17:240:17:27

Which means he can do this.

0:17:290:17:32

This.

0:17:320:17:33

And even this.

0:17:330:17:35

Charlie is a contortionist break-dancer and he's so flexible

0:17:350:17:39

he can make it look like there are no bones in his body at all.

0:17:390:17:42

People don't really know if they should be impressed by it,

0:17:420:17:45

if they should be disgusted by it.

0:17:450:17:46

There's always that thing of, "Eugh, I don't want to see it."

0:17:460:17:50

"Eugh!" It's kind of they have to watch it.

0:17:500:17:53

CHRIS AND XAND: Oh, we must watch.

0:17:530:17:55

So how does Charlie do these incredible moves?

0:17:550:17:58

Well, inside lots of Charlie's limbs,

0:17:580:18:01

he has super stretchy ligaments.

0:18:010:18:03

That's the soft tissue that holds all our bones together.

0:18:030:18:06

It means that he can bend certain joints

0:18:060:18:09

much further than most people.

0:18:090:18:12

Charlie trains all day, every day to make sure his ligaments

0:18:120:18:15

are as bendy as possible.

0:18:150:18:17

And he's just one of a handful of people in the world who can

0:18:170:18:20

do this without inflicting a serious injury on themselves.

0:18:200:18:23

Which is what would happen to me if I tried this.

0:18:240:18:27

Charlie's most dangerous move -

0:18:270:18:29

cartwheeling on his head.

0:18:290:18:31

It's so hard that there are very few people who even attempt it

0:18:310:18:35

and it took Charlie years to master.

0:18:350:18:37

Now that's amazing.

0:18:370:18:39

That's not how you grow organs.

0:18:480:18:50

Xand.

0:18:500:18:51

Here's Investigation Ouch!

0:18:510:18:52

This is how it's done.

0:18:550:18:56

Now don't worry, somebody isn't missing an ear.

0:18:560:18:59

This one was made in a laboratory.

0:18:590:19:01

Let's meet the real life Dr Frankenstein who built it,

0:19:010:19:04

and find out more about how replacement body parts are made.

0:19:040:19:08

This is Professor Alex Seifalian.

0:19:090:19:12

He is working at the Royal Free Hospital in London,

0:19:120:19:14

creating body parts out of a special substance called bioplastic.

0:19:140:19:18

So what are you making here?

0:19:200:19:21

We're making artery, to replace damaged artery in the body.

0:19:210:19:25

Now an artery is a blood vessel,

0:19:250:19:27

that carries blood from your heart out to the rest of your body.

0:19:270:19:31

And this machine is making artificial arteries

0:19:310:19:34

by squeezing liquid bioplastic over a tube.

0:19:340:19:37

This solidifies in water and then when you peel it off,

0:19:370:19:40

hey presto, you have an artery.

0:19:400:19:42

So this is 2mm, very small artery.

0:19:450:19:48

What's so amazing about this is I've handled real human arteries

0:19:500:19:54

and this is how they feel.

0:19:540:19:56

So could an artificial artery like this one

0:19:560:19:58

be put inside a human being?

0:19:580:20:00

Yes, it goes in the heart or it goes into the leg.

0:20:000:20:03

Lots of things can happen to arteries.

0:20:050:20:06

They can get injured, they can burst, they can get blocked.

0:20:060:20:09

That's what happens when you have a heart attack.

0:20:090:20:11

So if you can make an artificial artery that works,

0:20:110:20:14

you can save millions of lives.

0:20:140:20:16

But it's not just arteries Alex is creating here,

0:20:170:20:20

there are more complex organs being made too.

0:20:200:20:23

OK, this is ear scaffold.

0:20:250:20:28

Oh so it feels very much like a real ear.

0:20:280:20:30

Yes, indeed.

0:20:300:20:31

But you couldn't just sew this onto a human body, could you?

0:20:310:20:34

No, because you need to be covered with a stem cell.

0:20:340:20:37

Stem cells stop the body rejecting the new ear.

0:20:380:20:41

But what are they and how do they work?

0:20:410:20:45

Well, different parts of your body

0:20:450:20:46

are made up of different types of cells.

0:20:460:20:49

They're everywhere - your blood,

0:20:490:20:51

your brain,

0:20:510:20:52

and even your hair.

0:20:520:20:54

But stem cells live in your organs and bones too

0:20:540:20:56

and they're like spares.

0:20:560:20:58

They don't have a job yet

0:20:580:20:59

and they're waiting to be told what to do.

0:20:590:21:02

What's brilliant is that scientists have found a way

0:21:020:21:05

to programme stem cells, giving them specific jobs.

0:21:050:21:08

Feel your ear right now. All that gristly stuff, that's cartilage.

0:21:100:21:13

Now Alex takes stem cells from the person who needs the new ear

0:21:130:21:17

and he puts the stem cells onto the plastic ear

0:21:170:21:20

and he tells them to become cartilage cells.

0:21:200:21:23

The stem cells grow all over the plastic ear so that it won't

0:21:230:21:27

be rejected by the body.

0:21:270:21:28

But even with the magic stem cells, this still looks like a plastic ear.

0:21:290:21:34

It needs skin over it.

0:21:340:21:35

Now Alex has done the next bit of the procedure overseas

0:21:360:21:39

and it went like this.

0:21:390:21:40

Imagine I'm the patient.

0:21:420:21:44

He placed the artificial ear covered in stem cells

0:21:440:21:47

under the skin of the patient's arm,

0:21:470:21:49

so that it gets a good blood supply and skin grows all over it.

0:21:490:21:53

Then the ear covered in the patient's own skin is removed

0:21:530:21:57

and repositioned where you'd normally expect to find an ear.

0:21:570:22:00

Awesome.

0:22:000:22:02

But Alex doesn't stop at ears. Oh, no.

0:22:020:22:04

Two years ago, he performed the world's first

0:22:060:22:09

successful transplant of an artificial windpipe.

0:22:090:22:13

What's absolutely amazing about this, is that doctors are now

0:22:130:22:17

able to make replacement body parts that actually live inside your body.

0:22:170:22:22

Now it's early days,

0:22:220:22:23

but hopefully soon they'll be able to make any body part.

0:22:230:22:26

In the meantime, the next thing on Alex's list is a nose.

0:22:260:22:30

I wonder who's going to end up with this?

0:22:310:22:33

Your body is brilliant.

0:22:380:22:40

It can even repair itself if you get injured.

0:22:400:22:43

As this next boy will show you.

0:22:430:22:46

# If there's a bone to break

0:22:460:22:47

# He'll break it

0:22:470:22:48

# If there's a knee to graze

0:22:480:22:50

# He'll graze it

0:22:500:22:51

-# If there's an ankle to sprain

-# He'll sprain it

0:22:510:22:54

# He's the unluckiest kid. #

0:22:540:22:55

Your face has more blood vessels in it than anywhere else in your body.

0:22:580:23:03

Yep, that's a lot of blood vessels.

0:23:030:23:05

Up your nose there are little blood vessels close to the surface.

0:23:050:23:08

They're very delicate so a nose picking finger can break them,

0:23:080:23:11

making your nose bleed.

0:23:110:23:13

First, your body needs to plug the gap.

0:23:140:23:16

Using platelets that are you in your blood,

0:23:170:23:19

they stick together like glue and stop the bleeding.

0:23:190:23:22

A protein called fibrin arrives at the wound

0:23:240:23:27

and creates a big structure that makes a big, hard scab.

0:23:270:23:31

New skin cells work their way to the top.

0:23:320:23:35

Then everything is cleaned by plasmin.

0:23:350:23:38

This brilliant enzyme dissolves the scab

0:23:380:23:40

and everything is left looking good as new.

0:23:400:23:43

Not again.

0:23:430:23:44

Oh, dear.

0:23:460:23:47

# He's the unluckiest kid. #

0:23:470:23:49

Another patient has had a rather unusual accident.

0:23:500:23:53

Luckily, the team is ready to fix her.

0:23:530:23:56

In accident and emergency,

0:23:590:24:00

seven-year-old Amy has come in with...

0:24:000:24:03

A flower growing out of her head?

0:24:030:24:04

No, a sore foot and some very nice boots.

0:24:040:24:07

Yes, but what's wrong with her foot?

0:24:080:24:10

I'm going to go and get my toe checked to see

0:24:100:24:13

if it's broken cos my brother he...

0:24:130:24:16

Go on.

0:24:160:24:18

..he pushed me and I got my foot stuck in the chair.

0:24:180:24:21

Foot stuck in a what?

0:24:210:24:22

A chair.

0:24:220:24:24

How on earth?

0:24:240:24:25

It all happened five days ago.

0:24:250:24:27

Amy was at home in the lounge with her little brother.

0:24:290:24:32

He had his favourite show on the telly and he wasn't changing

0:24:320:24:35

the channel for anyone.

0:24:350:24:37

Well, you know what it's like when you're fave show is on.

0:24:370:24:40

To keep the peace, Amy decided it wasn't worth an argument,

0:24:400:24:43

so she thought she'd go upstairs and play.

0:24:430:24:46

As she got up she went to pick up her doll.

0:24:460:24:48

Go on then Amy, off you go.

0:24:490:24:50

But her brother thought she was going to grab the remote control

0:24:500:24:53

off him and pushed her away.

0:24:530:24:56

Amy went tumbling backwards, but her foot was trapped under the chair.

0:24:560:24:59

Well, that'll teach you for playing nicely Amy, ouch!

0:24:590:25:02

It really hurt that moment and stuff

0:25:030:25:05

and we thought it would get better but it didn't.

0:25:050:25:09

She might have got to grips with using crutches,

0:25:090:25:12

but her foot still hurts and she can't put any weight on it.

0:25:120:25:15

Which is a problem because Amy has some big plans on the horizon.

0:25:150:25:19

Well, I hope it's better in two weeks, cos it's my birthday and for

0:25:200:25:24

my birthday I'm doing ice skating and I need my toes to ice skate.

0:25:240:25:29

Yep, you certainly do.

0:25:300:25:31

So best to get you in to see Dr Adam Abraham.

0:25:350:25:37

Come through please. I like your boots.

0:25:390:25:42

Told you they were nice.

0:25:420:25:43

Yeah, but what about the toe?

0:25:430:25:46

So where's it the most painful, my love?

0:25:460:25:48

They're painful there.

0:25:480:25:49

OK. And does it hurt if I push in slightly?

0:25:500:25:53

Only a little bit.

0:25:530:25:55

OK, I think we need an X-ray just to make sure it's not broken.

0:25:550:25:58

So time for Amy to hot foot it to X-ray.

0:25:590:26:02

OK, nice and still for me.

0:26:050:26:06

If your feet were x-rayed right now, it would look like you had

0:26:080:26:11

twice the number of bones as your mum or dad's feet.

0:26:110:26:15

That's because when you're born, your feet contain soft cartilage.

0:26:150:26:19

As they grow, the cartilage develops into pieces of bone, but it's

0:26:190:26:22

not until you're about 18 that they fuse together

0:26:220:26:25

to make the 26 bones of an adult foot.

0:26:250:26:27

But has Amy broken any of her foot bones?

0:26:300:26:33

Time to find out.

0:26:330:26:34

That's your toe.

0:26:360:26:37

Now I can't see a break.

0:26:390:26:41

There could be a number of reasons for that,

0:26:410:26:43

one being that there wasn't a break to begin with, but she's either

0:26:430:26:47

done some damage to the tendons or she's just sprained it very badly.

0:26:470:26:51

Two, it's because it has been almost a week now.

0:26:510:26:53

If the break was bad, we would have seen it.

0:26:540:26:58

Regardless of the five, six day interval.

0:26:580:27:00

So it's good news and all the doctor needs to do is strap up her toe

0:27:000:27:05

to make sure it heals in the best position.

0:27:050:27:07

But does it mean that Amy will make it to the ice rink?

0:27:070:27:11

In two weeks.

0:27:110:27:12

Yeah, you've got plenty of time,

0:27:120:27:14

because that's almost three weeks from the original injury, isn't it?

0:27:140:27:17

I think it should be fine.

0:27:170:27:18

That's a relief.

0:27:180:27:20

Time to hop it, Amy, your ice rink awaits.

0:27:200:27:22

CHRIS AND XAND: Bye.

0:27:240:27:25

Next time in accident and emergency, Max's lip has ballooned.

0:27:270:27:30

We show you what your liver does.

0:27:320:27:35

Whoa.

0:27:350:27:36

And Chris finds out why we can't do without snot.

0:27:360:27:39

Oh there's a couple of nice ones on there.

0:27:390:27:41

Oh.

0:27:410:27:43

Until then, that's all from...

0:27:430:27:45

Operation Ouch!
