'He's Dr Chris.

0:00:220:00:24

'He's Dr Xand.

0:00:250:00:27

'And yes, we're twins.'

0:00:270:00:30

Do you know how brilliant your body really is?

0:00:300:00:33

My finger's got yellow pus in it.

0:00:330:00:36

-Well, we're going to show you.

-Yay!

0:00:360:00:38

In this series we'll be pushing our bodies to their limits...

0:00:380:00:42

I like the sound of this.

0:00:420:00:44

..by doing extraordinary experiments on each other.

0:00:440:00:47

-This is my sick.

-To uncover what goes on inside...

0:00:470:00:50

Ugh! that just came out of my ear.

0:00:500:00:53

..and out.

0:00:530:00:54

Wow, that's amazing!

0:00:540:00:56

From the bizarre...to the incredible.

0:00:560:00:59

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? Chris? Chris?

0:01:030:01:06

-Coming up...

-on Operation Ouch!

0:01:080:01:11

We blend up a liver to show you something amazing.

0:01:130:01:17

-Oh, wow!

-Oh!

0:01:170:01:18

What on earth is going on here?

0:01:180:01:21

You'll find out soon, Xand.

0:01:210:01:23

And I'm on a mission to get your snot.

0:01:230:01:26

Oh, there's a couple of nice ones on there!

0:01:260:01:28

But now...

0:01:280:01:31

Our first patient was expecting a normal day.

0:01:310:01:33

And now they've ended up in accident and emergency.

0:01:330:01:36

Let's see him get fixed.

0:01:360:01:38

This is accident and emergency in Manchester,

0:01:380:01:42

the place for all medical mishaps and...

0:01:420:01:44

What on earth's happened here?

0:01:440:01:47

Has he superglued his hands to his nose?

0:01:470:01:49

No, Xand. this is eight-year-old Max

0:01:490:01:51

and the problem is not with his nose.

0:01:510:01:53

A few minutes ago, I realised that my lip was all swollen.

0:01:540:01:59

-Did he say he had a swollen lip?

-Yes, look.

0:01:590:02:02

Oh, it is swollen! But why are you holding it?

0:02:020:02:07

When it touches my teeth it hurts.

0:02:070:02:10

It hurts if it touches your teeth, got it.

0:02:100:02:13

So how did Max's lip end up so large?

0:02:130:02:16

Well, it's all a bit of a mystery.

0:02:160:02:19

Max was having a normal day. He'd been to school, like normal.

0:02:200:02:24

And then afterwards he'd been swimming, like normal.

0:02:240:02:27

And then he came home, had one of his favourite meals.

0:02:270:02:31

Mm, meat pie. Yummy.

0:02:310:02:33

Then he sat down to watch his favourite cooking show.

0:02:330:02:36

This is making me hungry.

0:02:360:02:38

But just as they were getting to dessert,

0:02:380:02:40

Max felt something funny going on with his lip.

0:02:400:02:42

It started to tingle...

0:02:420:02:44

and then it grew...

0:02:440:02:46

and it grew...

0:02:460:02:48

-and it grew.

-Ouch!

0:02:480:02:50

It really stung when it started going really big.

0:02:500:02:54

I bet! And with such strange swelling,

0:02:540:02:57

let's open the case of Max's mystery mammoth mouth.

0:02:570:03:01

Has he had any allergic reactions in the past?

0:03:010:03:04

Yes. He's got allergies to peanuts and white fish.

0:03:040:03:07

OK, and he's not had any nuts or anything near him?

0:03:070:03:10

So Max doesn't think he's eaten nuts or white fish,

0:03:120:03:15

which he's allergic to.

0:03:150:03:16

But with symptoms like this, he's taking a medicine called

0:03:160:03:19

antihistamine, just in case it is an allergic reaction.

0:03:190:03:23

Well, here's someone who can bust that lumpy lip.

0:03:240:03:27

It's Dr Sara Syed.

0:03:270:03:29

So was it sore? Was it tingly?

0:03:300:03:32

-It was stinging.

-It was stinging, was it?

-Yeah.

-OK.

0:03:320:03:36

It didn't feel like your throat was getting tight or anything?

0:03:360:03:39

-No.

-No.

0:03:390:03:41

Dr Sara needs to give Max a thorough examination to find out

0:03:410:03:44

whether or not he's having an allergic reaction.

0:03:440:03:47

-Can you just say "ahh" for me?

-Ahh.

0:03:470:03:49

If he is, the biggest concern is

0:03:500:03:52

that it could get worse and cause his throat to swell up,

0:03:520:03:55

making it hard to breathe.

0:03:550:03:57

-OK, is that sore at all?

-No.

0:03:580:04:00

OK, there's no swelling at the back of your throat, which is good.

0:04:000:04:03

Luckily Max's throat and airways are clear, but what about his lip?

0:04:030:04:07

Is it from an allergy?

0:04:070:04:09

It looks like some form of allergic reaction, OK?

0:04:090:04:13

Just with there being the swelling and this tingling,

0:04:130:04:16

it kind of all fits in with that picture.

0:04:160:04:19

The good news is that the antihistamine has started to work

0:04:190:04:23

and another 20 minutes later, Max's lip is looking smaller.

0:04:230:04:27

-How are you feeling?

-Better.

-Yeah?

0:04:270:04:30

High five, antihistamine!

0:04:300:04:32

What exactly has made him have that allergic reaction

0:04:320:04:36

is a little bit of a mystery. It seems like his immune system's

0:04:360:04:39

just responded quite strongly to something.

0:04:390:04:42

It might be that Max has developed a new allergy.

0:04:420:04:45

To try and find out,

0:04:450:04:47

he'll return for an allergy test in a week's time.

0:04:470:04:50

We'll be back later to find out how he gets on.

0:04:500:04:53

-And now to our lab...

-Whoa!

0:04:570:04:59

..where we do incredible experiments...

0:04:590:05:02

Oh, looks disgusting.

0:05:020:05:04

..to show you how your body works.

0:05:040:05:06

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

0:05:060:05:09

And today's lab is all about amazing enzymes.

0:05:090:05:13

-Xand, your crackers.

-I'm what?

0:05:130:05:15

-Your crackers.

-Chris, this is no time for personal insults.

0:05:150:05:19

Get your crackers for the experiment.

0:05:190:05:22

Oh... Sorry.

0:05:220:05:25

Now, your body is full of loads of little proteins called enzymes,

0:05:250:05:28

which help to break down the food you eat

0:05:280:05:31

into chemicals your body can use.

0:05:310:05:34

For example, this cracker is made of starch, which your body can't use,

0:05:340:05:38

but in your spit you have an enzyme called amylase.

0:05:380:05:42

Now, the amylase enzyme breaks down the starch into sugar,

0:05:420:05:46

which your body can use.

0:05:460:05:48

This bit of the experiment you can try at home.

0:05:480:05:51

Get a cracker. Don't eat it.

0:05:510:05:53

Simply chew it up

0:05:530:05:55

and let it sit on your tongue and we'll see what happens.

0:05:550:05:58

'These crackers are going to start tasting very different.'

0:06:000:06:03

The savoury cracker is getting sweeter,

0:06:130:06:15

because the amylase in the saliva

0:06:150:06:17

is breaking down the starch into sugars, which are sweet.

0:06:170:06:20

You've made a real mess.

0:06:200:06:23

Why don't you try it and you'll notice the difference too?

0:06:240:06:27

So what's going on?

0:06:270:06:29

Well, the enzymes in our spit change the starch into sugar and

0:06:290:06:32

you've got lots of other enzymes around your body, all changing

0:06:320:06:35

substances from one thing to another, including in your liver.

0:06:350:06:40

Now, this is an animal liver but it's very similar to a human one.

0:06:400:06:43

This liver does loads of different jobs.

0:06:430:06:46

It's a really important chemical factory that extracts all

0:06:460:06:49

the nutrients from the foods you eat so that your body can use them.

0:06:490:06:53

But when food breaks down, your body sometimes makes poisonous toxins.

0:06:530:06:57

But don't worry, the enzymes in your liver make them safe.

0:06:570:07:00

One example of a toxin produced by your body is hydrogen peroxide.

0:07:000:07:04

Now hydrogen peroxide's actually used by hairdressers

0:07:040:07:07

to bleach people's hair.

0:07:070:07:09

Here we go, Xand.

0:07:090:07:10

There is some hydrogen peroxide.

0:07:100:07:12

Oh, great, are we going to do our hair?

0:07:120:07:14

No, we're going to do an excitement on the liver to find out how it

0:07:140:07:17

-breaks down poisonous hydrogen peroxide.

-Of course we are.

0:07:170:07:20

'So we're going to show you

0:07:200:07:22

'how enzymes change a poison and make it safe.

0:07:220:07:25

'Normally these processes take place inside the liver

0:07:270:07:30

'but we need to see them in action, so we're cutting it up

0:07:300:07:33

'and blending it and now all the enzymes are released

0:07:330:07:36

'and what goes on inside the liver

0:07:360:07:38

-'will now happen on the outside for us all to see.'

-Let's go.

0:07:380:07:42

OK. You hold that.

0:07:440:07:46

'So we're going to show you what happens when enzymes

0:07:460:07:49

'in the liver break down hydrogen peroxide.

0:07:490:07:52

'If this works it'll look pretty amazing.'

0:07:520:07:54

-Oh, wow!

-Oh!

0:07:540:07:57

'All that frothing might look dangerous,

0:07:570:07:59

'but it's actually the opposite.

0:07:590:08:01

'The liver enzymes are turning the dangerous hydrogen peroxide

0:08:010:08:04

'into harmless oxygen and water.

0:08:040:08:07

Oh, it's really good, there you go.

0:08:070:08:09

OK, now swirl it around a bit.

0:08:090:08:11

So all the bubbles in that foam are bubbles of oxygen.

0:08:110:08:14

We've put the liver in there and the enzymes in the liver are

0:08:140:08:17

detoxifying the hydrogen peroxide,

0:08:170:08:19

turning it into water and oxygen.

0:08:190:08:21

-Can we prove it's oxygen?

-Of course we can prove it's oxygen.

0:08:210:08:24

'Now, things don't burn without oxygen,

0:08:240:08:27

'so let's see if there is oxygen present in these bubbles.'

0:08:270:08:30

So this is one of our special scientific tapers,

0:08:300:08:33

which as you can see is glowing, but not on fire.

0:08:330:08:35

When I put it in the oxygen...

0:08:350:08:37

Whoa, that's really good! Whoa!

0:08:380:08:40

The smouldering taper is set on fire by the oxygen that's been created.

0:08:420:08:46

This shows that the enzymes in the liver have turned the

0:08:460:08:49

dangerous hydrogen peroxide into harmless water and oxygen.

0:08:490:08:53

This is exactly the same chemical reaction that occurs

0:08:530:08:56

inside your liver. It cleans up the toxic chemicals and makes them safe.

0:08:560:09:00

Can I have my hair done now?

0:09:000:09:02

-Nice to be out and about.

-Walking to the park, seeing friends.

0:09:060:09:09

But there are always dangers lurking on the street

0:09:090:09:12

and I'm not just talking about Xand.

0:09:120:09:14

I'm talking about street danger.

0:09:140:09:17

For example, there could be a car coming around this corner.

0:09:190:09:22

HORN SOUNDS Stop! I've got you covered, Chris.

0:09:220:09:25

There could be broken glass in the street.

0:09:270:09:29

Yep, already noticed and avoided. On we go.

0:09:290:09:32

And finally, there's the danger

0:09:320:09:34

of unidentified flying objects falling out of the sky.

0:09:340:09:37

Honestly Chris, I think that is extremely unlikely.

0:09:370:09:40

Oww! Oh.

0:09:420:09:44

Oh, look, a rogue pineapple's

0:09:440:09:46

just fallen out of the sky and onto Xand's foot.

0:09:460:09:49

-Admittedly, that was very unlikely.

-Unlikely and painful.

0:09:490:09:53

It's also a minor injury.

0:09:530:09:55

So what should you do if you bruise your foot?

0:09:590:10:01

The correct answer is C.

0:10:180:10:21

So to treat a bruised foot, you just do something very simple.

0:10:210:10:25

Put something cold on it to relieve the pain and reduce the swelling.

0:10:250:10:28

-How's that?

-That's great.

0:10:280:10:30

-Good enough to play football on?

-Oh, we forgot the football. Bother.

0:10:300:10:34

How does he do that?

0:10:350:10:37

So, to treat a bruised foot, put something cold on it,

0:10:370:10:40

but if you're worried, tell an adult.

0:10:400:10:43

Time to see how Max is getting on.

0:10:460:10:48

Let's head back to accident and emergency.

0:10:480:10:51

Back in Manchester, eight-year-old Max has returned to hospital

0:10:510:10:55

for an allergy test after his lip swelled up like this.

0:10:550:10:59

Wow! It was a whopper!

0:10:590:11:01

Max had been to school,

0:11:010:11:03

then swimming and then had dinner at home.

0:11:030:11:05

And all of a sudden his lip started to swell up like a big balloon.

0:11:070:11:11

So this is what you look like normally.

0:11:110:11:14

But the cause of his mega mouth is still a bit of a mystery.

0:11:140:11:19

Max is allergic to peanuts and white fish,

0:11:190:11:21

but he hadn't eaten either of those things that day.

0:11:210:11:24

However, Max has a theory.

0:11:240:11:27

Uh-oh, Mum's in trouble!

0:11:270:11:28

Mum said she was eating nuts and she touched me on my face.

0:11:280:11:33

I might have to hold my hands up to that cos we do eat nuts at home.

0:11:330:11:37

But we do keep them out of his way.

0:11:370:11:39

Well, it could be his mum but it could also be something new.

0:11:390:11:42

Enter allergy specialist nurse Sarah Allatt.

0:11:450:11:48

And gosh, she's a terrible speller.

0:11:480:11:50

No, Xand, she's putting a variety of allergy samples onto Max's arm

0:11:500:11:55

to see which ones get a reaction.

0:11:550:11:57

And it's not just food types.

0:11:570:12:00

This is dog.

0:12:000:12:01

She's also testing for things in the environment, including dogs,

0:12:010:12:05

-cats, grass and tree pollen.

-All done.

0:12:050:12:09

Now Max just has to wait.

0:12:090:12:11

The best thing to do if it itches is to blow.

0:12:110:12:14

It takes 15 minutes for the reaction to show up.

0:12:140:12:17

A white bump shows there's an allergy.

0:12:170:12:20

Wow, we've certainly got a few there.

0:12:200:12:22

So our tests today have said, yes,

0:12:220:12:26

you're still allergic to white fish and peanuts,

0:12:260:12:28

but what we've also learnt today is that you are allergic to cats.

0:12:280:12:32

So was Max playing with cats on the day his lip swelled up? No.

0:12:320:12:37

And you are allergic to grass.

0:12:370:12:39

Oh, was he roaming around like I do when I'm allowed?

0:12:390:12:42

No, Xand, he wasn't.

0:12:420:12:44

So we're still none the wiser about why his lip grew so big.

0:12:440:12:48

-Well, Max still has his theory.

-I think it was Mum.

0:12:480:12:51

-Your mum? That's nuts.

-Well, we'll never know.

0:12:530:12:57

-You can put your arm away now, Max.

-Bye.

-BOTH: Bye.

0:12:570:13:00

Still to come, we show you how your body heals a sprain.

0:13:030:13:07

I go on a snot mission.

0:13:070:13:09

Can we get a sample of your snot?

0:13:090:13:11

And his nose may look fine but Oscar needs it to be fixed.

0:13:130:13:17

It felt like it just went on the side.

0:13:170:13:19

Did you know that you lose

0:13:240:13:26

about 90 hairs every single day?

0:13:260:13:28

But luckily you've got between 90 and 140,000 hairs

0:13:280:13:32

on your head, so you can afford to lose a few.

0:13:320:13:34

Wow, that's amazing. And so is this.

0:13:340:13:37

An ordinary country lane.

0:13:370:13:40

And an ordinary car.

0:13:400:13:42

Looks like this guy's having a bit of engine trouble.

0:13:420:13:45

Poor chap. He's going to need a push.

0:13:450:13:48

Well, luckily, this lady is around to help.

0:13:480:13:51

-You look like you need a hand.

-She's going to push that car?

0:13:510:13:55

That is amazing Chris! It's a massive four by four.

0:13:550:13:59

It's way more amazing than that, Xand. Check this out.

0:13:590:14:02

This is Anastasia and her hair is so strong...

0:14:060:14:10

..she can, yes, even pull a car with it.

0:14:110:14:13

Crazy, I know.

0:14:140:14:16

Anastasia holds the world record for hanging weight from her hair,

0:14:160:14:20

a hair raising 53.4 kilograms -

0:14:200:14:23

that's the equivalent of two average seven-year-olds

0:14:230:14:26

hanging directly from her hair.

0:14:260:14:28

So how does she do it?

0:14:290:14:32

Well, human hair contains keratin.

0:14:350:14:38

It's an incredibly strong protein.

0:14:390:14:42

So tough, in fact, it's the same thing a rhinoceros horn is made of.

0:14:420:14:46

Anastasia has learned to use the strength of her hair

0:14:480:14:50

to pull massive cars like this.

0:14:500:14:53

And it takes a lot of preparation.

0:14:530:14:55

It takes 45 minutes. It takes two guys to plait the hair like a rope.

0:14:550:14:59

Turning her hair into a rope ensures the weight of the car is

0:15:010:15:04

evenly distributed across her head, so that no hair is pulled out.

0:15:040:15:08

But hair pulling is still an uncomfortable experience,

0:15:090:15:12

so Anastasia has trained herself to cope with the pain.

0:15:120:15:15

I can think of better ways of dealing with pain.

0:15:150:15:18

Yeah, like when you eat a cold ice cream and you get a brain freeze.

0:15:180:15:21

Not exactly, Xand. She's got a real skill.

0:15:210:15:24

Now that's amazing.

0:15:240:15:26

Your body can need mending in all sorts of ways

0:15:300:15:33

and we're going to meet some special teams that are trained to fix you.

0:15:330:15:37

Let me show you my ear.

0:15:380:15:40

Never put anything in your ear, by the way,

0:15:400:15:43

unless you're a doctor like me.

0:15:430:15:45

There is my ear drum.

0:15:450:15:46

It vibrates so we can hear sounds.

0:15:460:15:49

On my ear drum, you can see some old scars,

0:15:490:15:52

because it burst because of infection when I was younger.

0:15:520:15:55

Now, my ear drum works perfectly fine now,

0:15:550:15:58

but when I was eight, I had a problem called glue ear.

0:15:580:16:01

Now, that doesn't mean that my ears were actually producing glue.

0:16:010:16:05

Inside my right ear, it was producing gloopy, thick fluid,

0:16:050:16:09

like very thick snot, which meant I couldn't hear very well.

0:16:090:16:12

Well, believe it or not, this is very common - 80% of people

0:16:120:16:15

have had it by the time they're ten.

0:16:150:16:18

Glue ear can cause earache and sometimes it can go on its own,

0:16:180:16:21

but if you're struggling to hear,

0:16:210:16:23

surgery is required in your ear drum.

0:16:230:16:26

This is Kieran. He's at Royal Manchester Children's Hospital

0:16:260:16:30

and today he's having a tiny plastic tube fitted called a grommet.

0:16:300:16:33

-Now, do you know what these tubes are going to do?

-No.

-No?

0:16:330:16:37

The tubes sit in your ear drum and there's fluid behind your ear drum,

0:16:370:16:41

so they let the fluid drain out and that stops you getting earaches,

0:16:410:16:44

stops you getting infections and it stops you going deaf.

0:16:440:16:47

So to understand it properly, grommets sit in the ear drum.

0:16:470:16:51

There's a grommet in an ear drum just like mine earlier.

0:16:510:16:54

But that hole is very important -

0:16:540:16:58

it lets the air in to relieve any pressure build up.

0:16:580:17:01

-So will that be good to have it all fixed?

-Yeah.

0:17:010:17:04

Time to scrub up and get ready for surgery.

0:17:040:17:07

Carrying out the procedure today is Miss Jaya Nichani,

0:17:070:17:10

ear, nose and throat surgeon.

0:17:100:17:12

It usually settles down by itself.

0:17:140:17:17

It's when it won't settle down and they have problem with it

0:17:170:17:20

because they can't hear, that's when we've got to do something about it.

0:17:200:17:24

And that's exactly the case with Kieran.

0:17:240:17:27

The grommet itself is tiny, but then it is going into a tiny space.

0:17:270:17:31

So the first thing Jaya's going to do is stick a vacuum cleaner down there

0:17:310:17:35

and try and suck out some of the fluid

0:17:350:17:37

and then we've got to remove the glue, which is the sticky stuff.

0:17:370:17:40

Can you hear that glue coming out now? The noise?

0:17:400:17:43

There we go, glue. Out you come.

0:17:430:17:46

This is really satisfying, watching this.

0:17:460:17:48

I'm really, really enjoying this.

0:17:480:17:51

With the goo removed, Jaya can now put the grommet in place.

0:17:510:17:54

It's very precise work as Jaya places the grommet

0:17:540:17:57

exactly in the tiny cut she's made in Kieran's ear drum.

0:17:570:18:00

Whoa! There it is! That's great.

0:18:000:18:03

So Kieran has got quite small ear holes,

0:18:030:18:05

so imagine how hard it is to put something that small

0:18:050:18:08

in exactly the right place. It's amazing.

0:18:080:18:11

Kieran's got glue ear in both ears, so he gets two.

0:18:110:18:14

It means he'll be able to hear well and no more earaches. Brilliant!

0:18:140:18:18

The grommets will be staying in for up to six months.

0:18:180:18:20

Then they just fall out without him even noticing.

0:18:200:18:24

By then, Kieran should have outgrown the problem and be all better.

0:18:240:18:27

Let's see how he is after the op.

0:18:270:18:30

-Can you hear any differently now?

-Yeah.

0:18:300:18:33

-Can you hear your mum talking a bit more easily?

-Yeah.

0:18:330:18:35

Well, that's great. Give me a high five.

0:18:350:18:38

When you're young, the little tubes inside your head

0:18:380:18:41

that connect your ears and your nose get easily blocked,

0:18:410:18:45

and that's what's happened to Kieran. That's why he needs grommets.

0:18:450:18:48

But as you get older, the tubes get bigger and you outgrow the problem.

0:18:480:18:53

Now, that's absolutely amazing to get that much benefit

0:18:530:18:56

from something half the size of a grain of rice.

0:18:560:18:59

This next boy may be accident prone,

0:19:040:19:06

but his body is brilliant at mending itself.

0:19:060:19:09

Just like yours.

0:19:090:19:11

# If there's a bone to break, he'll break it

0:19:110:19:14

# If there's a knee to graze, he'll graze it

0:19:140:19:17

# If there's an ankle to sprain, he'll sprain it

0:19:170:19:19

# He's the unluckiest kid. #

0:19:190:19:22

Ligaments are attached to your bones and they're strong and stretchy.

0:19:250:19:29

But if they're stretched too far they can tear,

0:19:290:19:31

this is called a sprain.

0:19:310:19:33

Ligaments tell your blood vessels they need help urgently,

0:19:330:19:36

because blood contains healing white blood cells.

0:19:360:19:39

So it sends blood gushing to the sprain.

0:19:420:19:44

The area swells up, protecting your vulnerable joint from moving.

0:19:440:19:48

It gets hot too, so bacteria don't want to live there.

0:19:480:19:52

But if it swells for too long, then scar tissue can build up.

0:19:530:19:56

The only way to stop that is to keep it cool.

0:19:560:19:59

Back inside, white blood cells get rid of the damage,

0:20:000:20:03

new ligament cells arrive.

0:20:030:20:05

After a few weeks, the ligaments get stronger,

0:20:050:20:08

so you're back on your feet.

0:20:080:20:10

Watch out! Ooh, unlucky.

0:20:120:20:15

# He's the unluckiest kid. #

0:20:150:20:17

It's time for Investigation Ouch.

0:20:180:20:21

And welcome to Manchester city centre.

0:20:210:20:23

Have you ever wondered what all this activity

0:20:240:20:27

does to the air you breathe in? Well, I'm about to find out.

0:20:270:20:30

When you breathe in air, your lungs transfer the oxygen

0:20:320:20:36

to your blood to keep your body going.

0:20:360:20:38

But your lungs also have to work hard to keep pollution out.

0:20:380:20:41

To do that, they need mucus and snot.

0:20:410:20:45

That's why for my investigation...

0:20:450:20:47

I'm going to need some snot!

0:20:470:20:49

I'll be collecting snot from the city and the seaside

0:20:490:20:53

to see what these two different environments throw at our

0:20:530:20:56

-lungs every time we breathe in.

-SHE LAUGHS

0:20:560:21:00

First up, the city.

0:21:000:21:02

-We want a sample of your snot.

-What?

0:21:020:21:04

You want my bogies? That's weird!

0:21:040:21:07

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

0:21:070:21:09

Well, that's the city sorted, but what about if you live by the sea?

0:21:090:21:13

I'm now at Weston Super Mare.

0:21:130:21:15

-Can we get a sample of your snot?

-Yeah!

-Do we have to?

0:21:150:21:20

Yeah!

0:21:200:21:22

It's a good haul, actually.

0:21:220:21:24

But this was going to be your breakfast, wasn't it?

0:21:240:21:27

Now we're going to take it back to the lab.

0:21:270:21:30

So now I've got a load of snot, let's see what's in it.

0:21:300:21:33

-There you are.

-Meet Dr Kelly Berube,

0:21:330:21:36

she's an expert on air pollution

0:21:360:21:38

at Cardiff University

0:21:380:21:39

and I've got a challenge for her.

0:21:390:21:41

So Kelly, I have taken nasal swabs from the city and from the seaside.

0:21:410:21:46

-OK.

-Now I want you to tell me which is which.

0:21:460:21:50

That's not going to be a problem Chris, easy peasy.

0:21:500:21:53

-Really?

-Yeah.

0:21:530:21:56

Kelly's putting each sample under her microscope to see what's

0:21:560:21:59

in it and work out where it's from.

0:21:590:22:02

This sample is going into the seaside pile.

0:22:020:22:04

I'm saying that that's going to be city.

0:22:040:22:07

Let's have a count up and see how she did.

0:22:080:22:10

That's correct.

0:22:100:22:12

Correct. Correct.

0:22:120:22:15

Correct, correct, correct.

0:22:150:22:18

How were you able to do that so easily?

0:22:180:22:21

Well, I started off with the fact that cities have more pollution.

0:22:210:22:25

The ones that had the most soot on them, I put them in the city pile

0:22:250:22:28

and the ones that didn't I put them on the seaside.

0:22:280:22:31

You've got snot up your nose and liquidy mucus all the way

0:22:310:22:35

down your airways into your lungs, where they trap pollution particles

0:22:350:22:39

and, this is where mucus is brilliant, it actually helps

0:22:390:22:42

your body get rid of those particles.

0:22:420:22:44

But if it's bombarded with too much pollution, it can't cope,

0:22:440:22:47

as we're going to show you.

0:22:470:22:50

This is a scanning electron microscope.

0:22:540:22:57

It's one of the most powerful microscopes in the world

0:22:570:23:00

and to replace it would cost almost £1 million.

0:23:000:23:03

It's expensive because it can magnify up to two million times more

0:23:030:23:07

than a normal microscope.

0:23:070:23:09

Each of these metal tubes contains little samples of lung tissue

0:23:090:23:12

and you're about to see them close up on this awesome bit of kit.

0:23:120:23:16

Kelly, what are we looking at here? What's this?

0:23:160:23:19

This is the surface of the lung and we have these cilia.

0:23:190:23:22

These are little hairs and they move mucus and to breathe out.

0:23:220:23:26

So basically, all the way through the air tubes

0:23:260:23:29

from our nose down into our lungs we have these

0:23:290:23:31

what look like hairs

0:23:310:23:33

and they move in time and shift mucus that's trapped stuff

0:23:330:23:37

we don't want in our lungs back up, so we can cough it out or spit it.

0:23:370:23:41

-Yeah, clean our lungs so we can breathe better.

-Or pick it.

-Yes.

0:23:410:23:44

So that was a healthy lung. This is an extremely diseased lung.

0:23:440:23:49

This person has been breathing in dirty, industrial air 24/7

0:23:490:23:52

over a very long period of time.

0:23:520:23:55

The cilia are destroyed and that's a particle of diesel.

0:23:550:23:59

Remember we saw the cilia? Well, here they've all collapsed.

0:23:590:24:02

So it looks like almost a field of grass,

0:24:020:24:05

where all the blades of grass have been flattened.

0:24:050:24:07

-Oh yeah, definitely.

-So if those cilia are flattened,

0:24:070:24:10

they can no longer move the mucus back up and get rid of stuff?

0:24:100:24:13

Yeah, so now that stuff is stuck in there.

0:24:130:24:17

But that was a lung under extreme, dirty conditions.

0:24:170:24:19

Although the air from our cities

0:24:190:24:21

is more polluted than the air by the seaside,

0:24:210:24:23

you shouldn't worry too much, because the mucus in your lungs

0:24:230:24:26

traps the pollution. It then gets wafted up by the cilia

0:24:260:24:30

in our airways and you can cough it up or blow it out your nose.

0:24:300:24:33

Proving your body is brilliant at cleaning its airways,

0:24:330:24:37

and that's whether you live by the sea or in the city.

0:24:370:24:39

Time to head back down to accident and emergency.

0:24:440:24:47

Here's another curious case.

0:24:470:24:49

In Manchester, 11-year-old Oscar has been brought to hospital

0:24:510:24:54

by his mum when he came home from football with a sore nose.

0:24:540:24:58

Playing football yesterday, at football training.

0:24:580:25:01

-We were winning 1-0...

-Go on.

0:25:010:25:05

..and someone elbowed me by accident

0:25:050:25:07

and it felt like it just went on the side.

0:25:070:25:10

Well, I'd definitely stop prodding it, then.

0:25:100:25:13

So, how exactly did this nose bending accident happen?

0:25:130:25:16

It was football training at school and Oscar was in goal.

0:25:190:25:23

His team were one up.

0:25:230:25:25

-They look a bit out of breath.

-And the crowd was going wild.

0:25:250:25:28

But the opposition were putting the pressure on

0:25:290:25:32

and the ball was heading Oscar's way.

0:25:320:25:34

Oh, where's the defence? He's clean through!

0:25:340:25:37

Oscar ran out to kick the ball clear...

0:25:370:25:40

..when all of a sudden there was a smash.

0:25:420:25:44

His nose collided with his opponent's elbow.

0:25:440:25:48

Yellow? I'd have gone for red, but I guess ref NOSE best.

0:25:480:25:51

That was terrible, Xand.

0:25:510:25:54

Oscar's nose might not look that bent

0:25:540:25:56

but with an accident like this

0:25:560:25:58

-there's a good chance it could be broken.

-It feels weird.

0:25:580:26:02

I bet it does, so let's get that weird-feeling nose seen to.

0:26:020:26:05

Over to ear, nose and throat specialist,

0:26:050:26:07

Mr Baskaran Ranganathan.

0:26:070:26:10

He'll find out if anything's damaged.

0:26:100:26:13

-Is it sore down here?

-No.

-OK.

0:26:130:26:16

The nasal bone probably is just broken in one point

0:26:160:26:19

so that it's shifted the bone to one side.

0:26:190:26:22

With a break like this, that means only one thing - an operation.

0:26:220:26:27

Inside your nose, the tip is made of flexible cartilage,

0:26:290:26:32

but higher up there are two thin bones,

0:26:320:26:34

which make up your nasal bone.

0:26:340:26:36

When these get a bang they can break easily

0:26:360:26:39

and need surgery to push them back into place.

0:26:390:26:41

Oscar's had a general anaesthetic, so he can't feel a thing

0:26:450:26:48

and now it's down to Mr Baskaran to straighten his sniffer.

0:26:480:26:51

The doctor uses forceps to pull the bones back into line.

0:26:520:26:56

This might look nasty, but if the bones aren't straightened up,

0:26:560:27:00

Oscar could have breathing problems for life.

0:27:000:27:04

There's a few final adjustments and before he NOSE it,

0:27:040:27:07

his nose is normal again.

0:27:070:27:09

Strapped up with support strips across the bridge of his nose,

0:27:090:27:13

it's all over.

0:27:130:27:15

And an hour later he's woken up.

0:27:150:27:17

Well, Mum's happy, but what do you think?

0:27:200:27:22

It's straight now and I can play football.

0:27:220:27:25

Well, hold your horses, your nose needs six to eight weeks to heal

0:27:250:27:28

before you can get back in goal, but for now, at least you're off home.

0:27:280:27:32

BOTH: Bye!

0:27:320:27:33

Next time, Courtney's ear needs flushing...

0:27:350:27:38

..Xand does some painting with his wee...

0:27:400:27:42

..and we meet some creepy crawlies

0:27:440:27:46

that are a bit too close for comfort.

0:27:460:27:49

Oh, it's moving!

0:27:490:27:51

-So that's it until next time.

-Bye!

0:27:510:27:54
