1:20:56 > 1:21:00Hi, there! This button fell off my lab coat yesterday,
1:21:00 > 1:21:03so I've just been sewing it back on.
1:21:03 > 1:21:07There! Good as new.
1:21:07 > 1:21:09BLEEPING
1:21:09 > 1:21:13I hear a beep, I see a flash, I wonder what they're going to ask.
1:21:16 > 1:21:17TOGETHER: Hi, Nina!
1:21:17 > 1:21:19Hi, guys!
1:21:19 > 1:21:23- We've got a question for you. - What are bellybuttons for?
1:21:23 > 1:21:26A great question, what are bellybuttons for?
1:21:26 > 1:21:28I've often wondered about that.
1:21:28 > 1:21:31Why don't you come down to the lab and we'll investigate?
1:21:31 > 1:21:35- TOGETHER: See you soon, Nina! Bye!- Bye!
1:21:35 > 1:21:39I need some help to answer this one and I know just who to ask.
1:21:39 > 1:21:41OK, Neurons, time to get to work.
1:21:59 > 1:22:01ALL: Neurons at the ready, Nina!
1:22:01 > 1:22:05Today's question is, what are bellybuttons for?
1:22:05 > 1:22:09Which Neuron do you think will be most useful in finding the answer?
1:22:09 > 1:22:11- Me!- Me!- Me!- Me!- Me!- Me!
1:22:11 > 1:22:14Will it be...Fabulous Felix?
1:22:14 > 1:22:18I can help so very much, if you need the sense of touch.
1:22:18 > 1:22:20Will it be...Beautiful Belle?
1:22:20 > 1:22:24I send messages to brain from ear, if there's a sound I help you hear.
1:22:24 > 1:22:26Will it be...Lovely Luke?
1:22:26 > 1:22:31For looking and seeing day or night, I help you with your sense of sight.
1:22:31 > 1:22:33Will it be...Awesome Ollie?
1:22:33 > 1:22:37If it's pongy but you can't tell, my messages help your sense of smell.
1:22:37 > 1:22:40Or will it be...Baby Bud?
1:22:40 > 1:22:44Sour, salty, bitter or sweet, I'm your taste buddy when you eat.
1:22:44 > 1:22:47BEEPING
1:22:47 > 1:22:49It's Luke!
1:22:49 > 1:22:51Yes!
1:22:51 > 1:22:55ALL: Go, Luke! Go, Luke! Go, Luke! Go, Luke!
1:22:55 > 1:22:58Go, Luke! Go, Luke! Go, Luke!
1:22:58 > 1:23:02Cool, Nina, I'll be looking out to help you.
1:23:02 > 1:23:05Today's question - what are bellybuttons for?
1:23:05 > 1:23:07Since our bellybutton is something we see,
1:23:07 > 1:23:10Luke, our sight Neuron, will help us today.
1:23:10 > 1:23:14Stand by, Neurons, I may need help from all of you.
1:23:14 > 1:23:18I need to get the lab ready before the experimenters arrive.
1:23:19 > 1:23:24Izzy likes rainbows, Kaleel like basketball and Laney loves drawing,
1:23:24 > 1:23:27but they all want to know what bellybuttons are for,
1:23:27 > 1:23:30so today, for one day only,
1:23:30 > 1:23:33Izzy, Kaleel and Laney become the experimenters!
1:23:35 > 1:23:38- Hi, guys!- Hi, Nina!
1:23:38 > 1:23:40Welcome to my science lab!
1:23:40 > 1:23:43Now you asked, what are our bellybuttons for,
1:23:43 > 1:23:47which is a great question, but why do you want to know?
1:23:47 > 1:23:50My bellybutton doesn't seem to do anything.
1:23:50 > 1:23:52Do the rest of you have bellybuttons?
1:23:52 > 1:23:54- Yes.- Yes, we do.
1:23:54 > 1:23:56What, all of you?
1:23:56 > 1:23:59- ALL: Yes!- I'm joking, I've got a belly button too.
1:23:59 > 1:24:03We're going to investigate to find out more about bellybuttons
1:24:03 > 1:24:07and for our first experiment we'll use our senses.
1:24:07 > 1:24:11ALL: Woo-woo! A senses experiment! We're ready, Nina!
1:24:11 > 1:24:16We know we all have bellybuttons, do you know anyone else who has one?
1:24:16 > 1:24:18- My sister.- My friends at school.
1:24:18 > 1:24:22Everyone has a bellybutton. Where is your bellybutton?
1:24:22 > 1:24:25- In your tummy. - Where exactly on your tummy?
1:24:25 > 1:24:30- In the middle.- Right, our bellybutton is in the middle of our tummy,
1:24:30 > 1:24:32just like on this dolly.
1:24:32 > 1:24:36Let's have a look at some photos of bellybuttons.
1:24:37 > 1:24:41Ha-ha! How would you describe this bellybutton?
1:24:41 > 1:24:44- Got a hole.- That's right, lots of bellybuttons go in the way,
1:24:44 > 1:24:48like this one, and we often call these innies.
1:24:48 > 1:24:50But not all bellybuttons do that.
1:24:51 > 1:24:56Ha-ha, some people have outie bellybuttons, like this one,
1:24:56 > 1:25:00that stick out a little bit. Do any of you guys have an outie?
1:25:00 > 1:25:01- Yes.- I do!
1:25:01 > 1:25:03You both have outies?
1:25:03 > 1:25:08Nobody knows for sure why some people have innies and some outies.
1:25:08 > 1:25:12I myself have an innie, but it doesn't matter what kind you have.
1:25:12 > 1:25:17OK, let's have a look at one more bellybutton.
1:25:17 > 1:25:21Ha-ha-ha!
1:25:21 > 1:25:25'Whoa! That's a strange looking bellybutton!'
1:25:25 > 1:25:28Whose bellybutton do you think it might be?
1:25:28 > 1:25:29A monkey's.
1:25:29 > 1:25:32Good guess. Let's see, shall we?
1:25:34 > 1:25:35Oh!
1:25:35 > 1:25:38- It's a puppy!- Yes!
1:25:38 > 1:25:41Humans aren't the only ones with bellybuttons,
1:25:41 > 1:25:44animals have them, too, like dogs and cats.
1:25:44 > 1:25:47You usually can't see them, they're covered in fur.
1:25:47 > 1:25:50So we now know that everyone has a bellybutton
1:25:50 > 1:25:54in the middle of their tummies and so do lots of animals.
1:25:54 > 1:25:57Some people have an innie and some people have an outie
1:25:57 > 1:26:00but it doesn't matter what type we have.
1:26:00 > 1:26:03We still don't know what why.
1:26:03 > 1:26:07To find out more we need to go and see a very special machine,
1:26:07 > 1:26:10- so let's go, experimenters! - ALL: Yeah!
1:26:13 > 1:26:15Off we go for another adventure.
1:26:15 > 1:26:19Nina said, we are going to see a special kind of machine.
1:26:19 > 1:26:23Maybe it's a noisy, spinning washing machine.
1:26:23 > 1:26:26I hope it's a sandwich-making machine.
1:26:26 > 1:26:29We'll soon find out, Neurons, we're here!
1:26:29 > 1:26:33- Are you excited about it?- Yes.
1:26:33 > 1:26:35Hi, Lucy. Hi, Yvonne.
1:26:35 > 1:26:39- Hi, Nina.- We've come to a clinic which helps mummies having babies.
1:26:39 > 1:26:45and as you can see from Yvonne's big tummy, she's having a baby.
1:26:45 > 1:26:48This is Lucy, she's a midwife who works here.
1:26:48 > 1:26:50You have a special machine
1:26:50 > 1:26:53that lets you see the baby inside a mummy's tummy?
1:26:53 > 1:26:57It's an ultrasound machine. Will we look at Yvonne's baby?
1:26:57 > 1:26:59ALL: Yes, please.
1:27:03 > 1:27:08Mmm, that doesn't smell like the nice jelly you have with ice cream.
1:27:08 > 1:27:12That's right, Ollie, you can't eat this jelly.
1:27:14 > 1:27:18The place where a baby grows inside a mummy is called the womb.
1:27:18 > 1:27:21The womb is a special space in a mummy's tummy
1:27:21 > 1:27:24full of a liquid that's a bit like water.
1:27:24 > 1:27:28The ultrasound machine lets us see the baby
1:27:28 > 1:27:32by creating a picture on that screen.
1:27:32 > 1:27:37I can see the baby, but it looks so small.
1:27:37 > 1:27:41It is small, Luke. Babies start off being teeny tiny,
1:27:41 > 1:27:44but they grow bigger in their mummy's womb.
1:27:44 > 1:27:48Babies can grow there because of something called an umbilical cord.
1:27:48 > 1:27:51The umbili...what, Nina?
1:27:51 > 1:27:53The umbilical cord, Bud.
1:27:53 > 1:27:58Here is a drawing of a baby inside its mummy's womb.
1:27:58 > 1:28:03Can you see this long thin thing that looks like a piece of string
1:28:03 > 1:28:06- joining the baby to its mummy? - ALL: Yes.
1:28:06 > 1:28:11That's the umbilical cord. Now, where does the cord join the baby?
1:28:11 > 1:28:16- On its belly.- Yes, right where our bellybuttons are.
1:28:16 > 1:28:17Once the baby's born,
1:28:17 > 1:28:22it doesn't need an umbilical cord any more, so a doctor cuts it off.
1:28:22 > 1:28:24Ooh! Does that hurt, Nina?
1:28:24 > 1:28:29No, it doesn't hurt at all, Felix, it's like having your hair cut.
1:28:29 > 1:28:32After the cord's gone, all that is left is a little bump,
1:28:32 > 1:28:35which is the baby's bellybutton.
1:28:35 > 1:28:38Can anyone see the baby's umbilical cord?
1:28:38 > 1:28:41I can. I can see it.
1:28:41 > 1:28:45Can you? Well spotted! Ha-ha!
1:28:45 > 1:28:50- Would you like to hear the baby's heart beating?- ALL: Yes, please.
1:28:51 > 1:28:53HEARTBEAT
1:28:55 > 1:28:58That sounds amazing, Nina.
1:28:58 > 1:29:03Isn't it, Belle? Thank you for showing us the ultrasound machine.
1:29:03 > 1:29:04You're welcome.
1:29:04 > 1:29:08- Thank you for letting us look at your baby.- My pleasure, Nina.
1:29:08 > 1:29:13We discovered that our bellybutton is left over from the umbilical cord
1:29:13 > 1:29:16we all had when we were in our mummy's womb.
1:29:16 > 1:29:18What does an umbilical cord do?
1:29:18 > 1:29:22I've got an experiment that will show us the answer.
1:29:22 > 1:29:26- Let's head back to the lab! Thanks again, bye.- ALL: Bye!
1:29:27 > 1:29:32OK, we're going to pretend that this is a mummy's womb inside her tummy.
1:29:32 > 1:29:36I need someone to go inside and pretend to be a baby.
1:29:36 > 1:29:40Izzy, hand up first! On you go.
1:29:40 > 1:29:43This is great, I love pretending.
1:29:43 > 1:29:47We're going to pretend this tube is an umbilical cord.
1:29:47 > 1:29:51An umbilical cord's a bit like a drinking straw.
1:29:51 > 1:29:56Things can travel inside it, like drinking liquid through a straw.
1:29:56 > 1:30:00We're also going to pretend these balls are important things
1:30:00 > 1:30:02a baby needs to help it grow.
1:30:02 > 1:30:06- Tell me, what do you think those things might be?- Food.
1:30:06 > 1:30:10Food will help the baby grow big and strong.
1:30:10 > 1:30:14That's right, Bud, these balls are our pretend food,
1:30:14 > 1:30:17the baby needs two other things to help it grow.
1:30:17 > 1:30:22- Water?- That's right, pretend water and these are pretend air.
1:30:22 > 1:30:26Air is the invisible gas all around us that we breathe in
1:30:26 > 1:30:31and I need you guys to roll these balls along the umbilical cord
1:30:31 > 1:30:33into the pretend womb.
1:30:33 > 1:30:36OK, get rolling!
1:30:39 > 1:30:43You can catch them at the end, Izzy. Oh, well done.
1:30:46 > 1:30:49Ha-ha-ha.
1:30:49 > 1:30:52Very good. When the baby's in its mummy's tummy,
1:30:52 > 1:30:56it can't eat, drink or breathe on its own like we can,
1:30:56 > 1:30:59so its mummy gives the baby food, water and air
1:30:59 > 1:31:04through the umbilical cord, which helps the baby to grow.
1:31:04 > 1:31:09There are some yellow balls that are already inside our pretend womb,
1:31:09 > 1:31:13so, Izzy, can I get you to put the yellow balls into the tube
1:31:13 > 1:31:16and pass them back through to us?
1:31:16 > 1:31:18OK.
1:31:20 > 1:31:24Push it, push it! Oh, here it comes!
1:31:24 > 1:31:25- You got it?- I have.
1:31:25 > 1:31:29The baby can't go to the bathroom and use the toilet like we can,
1:31:29 > 1:31:34these yellow balls are the waste the baby needs its mummy to get rid of.
1:31:34 > 1:31:38The umbilical cord helps a baby to grow in its mummy's womb.
1:31:38 > 1:31:42The cord brings the baby food, water and air
1:31:42 > 1:31:45and it takes away the waste, like poo and wee!
1:31:45 > 1:31:47- Yuck!- Ha ha ha!
1:31:47 > 1:31:52# Nina and the Neurons! #
1:31:52 > 1:31:55Your question - what are bellybuttons for?
1:31:55 > 1:31:57I think we've answered it.
1:31:57 > 1:32:01Everyone has a bellybutton in the middle of their tummy,
1:32:01 > 1:32:06we were lucky enough to see a baby growing inside its mummy's tummy
1:32:06 > 1:32:08in a space called the womb.
1:32:08 > 1:32:12The baby was joined to her by the umbilical cord.
1:32:12 > 1:32:16We found out the mummy's body uses the umbilical chord
1:32:16 > 1:32:19to give the baby the food, water and air it needs
1:32:19 > 1:32:20and take away waste.
1:32:20 > 1:32:25When the baby's born, it doesn't need the umbilical cord any more,
1:32:25 > 1:32:27so the doctors cut the cord off
1:32:27 > 1:32:30and the little bumpy bit of skin that's left over
1:32:30 > 1:32:33is what we call our bellybutton.
1:32:33 > 1:32:38- I hope that's answered your question.- ALL: Thanks, Nina, bye!
1:32:38 > 1:32:39Bye!
1:32:41 > 1:32:45If you want to find out more about the science all around us,
1:32:45 > 1:32:49go to the Nina section on the CBeebies website. Have fun!
1:32:49 > 1:32:52- Hearts beating.- Lungs breathing.
1:32:52 > 1:32:54- Fingers feeling.- Mouths eating.
1:32:54 > 1:32:56And don't forget your brain!

1:33:45 > 1:33:48Ah, it's been such a great day, man,
1:33:48 > 1:33:53seeing that lovely little baby growing inside its mummy's womb.
1:33:53 > 1:33:55It's been a marvellous day.
1:33:55 > 1:33:59I'm so glad that cutting the umbilical cord doesn't hurt.
1:33:59 > 1:34:03Everyone's body is different but they're all brilliant.
1:34:03 > 1:34:05See you soon. Bye!
