1:20:531:20:55

Oh, hello there! I love this experiment. Hee-hee.

1:20:571:21:01

I'm trying to see how far away I can get from the glass

1:21:021:21:06

and still drink the juice.

1:21:061:21:08

-Yes, I managed to get a drink!

-BEEP BEEP

1:21:151:21:19

I hear a beep, I see a flash. I wonder what they're going to ask.

1:21:191:21:24

-ALL: Hi, Nina!

-Hello!

1:21:271:21:30

-We've got a question for you.

-Why do we need blood in our body?

1:21:301:21:35

That's a great question. Why do we need blood in our body?

1:21:351:21:39

Our bodies have blood moving around them but what does it do?

1:21:391:21:43

Why not come down to my lab and we'll investigate.

1:21:431:21:48

ALL: See you soon, Nina. Bye!

1:21:481:21:53

I'll need help to answer this one and I know who to ask.

1:21:531:21:56

-OK, Neurons.

-Time to get to work!

1:21:561:21:59

ALL: Neurons at the ready, Nina.

1:22:151:22:18

Today's question is, "Why do we need blood in our body?"

1:22:181:22:22

Which Neuron will be most useful to answer that?

1:22:221:22:26

ALL: Me! Me! Me! Oh, me!

1:22:261:22:28

Will it be fabulous Felix?

1:22:281:22:30

I can help so very much if you need the sense of touch.

1:22:301:22:35

Will it be beautiful Belle?

1:22:351:22:37

I send messages to brain from ear. If there's a sound, I'll help you hear.

1:22:371:22:42

-Will it be lovely Luke?

-For looking and seeing, day or night,

1:22:421:22:46

I'll help with your sense of sight.

1:22:461:22:49

-Will it be awesome Ollie?

-If it's pongy or whiffy but you can't tell,

1:22:491:22:53

-my messages help your sense of smell.

-Or will it be baby Bud?

1:22:531:22:57

Sour, salty, bitter or sweet, I'm your taste buddy whenever you eat!

1:22:571:23:01

-It's Luke!

-Yes!

1:23:061:23:09

ALL: Go, Luke! Go, Luke! Go, Luke!

1:23:091:23:11

Go, Luke! Go, Luke! Go, Luke!

1:23:111:23:14

Cool, Nina. I'll be looking out to help you.

1:23:141:23:19

Today's question is, "Why do we need blood in our body?"

1:23:191:23:22

Blood is a red colour we can see,

1:23:221:23:24

so Luke, our sight Neuron, is helping me.

1:23:241:23:27

Stand by, Neurons. I may need help from all of you.

1:23:271:23:31

I'll get the lab ready before the experimenters arrive.

1:23:311:23:35

George likes football. Ryan likes curries and Gary loves superheroes.

1:23:361:23:41

But they all want to know why we need blood in our body.

1:23:411:23:45

So today, for one day only, George, Ryan and Jack are the Experimenters!

1:23:451:23:50

-Hi, guys!

-ALL: Hi, Nina!

1:23:521:23:54

Welcome to my science lab. Come in.

1:23:541:23:58

Now, you asked "Why do we need blood in our body?"

1:23:581:24:02

A great question but why do you want to know?

1:24:021:24:05

If we fall over and cut ourselves, sometimes blood comes out.

1:24:051:24:11

We want to know why blood is in our body.

1:24:111:24:13

Yes, if we cut ourselves, sometimes a bit of blood comes out

1:24:131:24:17

but it's nothing to be afraid of because it usually stops quickly.

1:24:171:24:22

There's lots to find out so let's start by using our senses.

1:24:221:24:27

ALL: Woop-woo! Our senses experiment. We're ready, Nina!

1:24:271:24:31

Blood is a runny liquid in our bodies.

1:24:311:24:34

We don't have any blood here

1:24:341:24:36

but we do have a runny liquid in these beakers.

1:24:361:24:40

Water. I've added some colouring so we can see it better.

1:24:401:24:44

Let's count the beakers together!

1:24:441:24:47

ALL: One, two, three, four, five.

1:24:471:24:51

Yes, we have five beakers of coloured water.

1:24:511:24:54

Does that look like a lot of water?

1:24:541:24:57

-Quite a lot.

-That's right.

1:24:571:25:00

Each beaker has one litre of coloured water in it.

1:25:001:25:03

And someone about my size has about five litres of blood inside them.

1:25:031:25:09

Which is all five of these beakers.

1:25:091:25:11

How much blood do you think children's bodies have?

1:25:111:25:15

-A bit less?

-Well, a child about your age and size might have

1:25:151:25:19

about two and half litres of blood inside them which is this much.

1:25:191:25:24

Wow, Nina. That's a lot of blood.

1:25:241:25:27

I know, Luke, our bodies do have quite a lot of brilliant blood

1:25:271:25:32

but where is it all?

1:25:321:25:34

This is a picture of the inside of our bodies

1:25:341:25:38

and these red lines are what we call blood vessels.

1:25:381:25:42

Blood vessels? Oooh, I like the sound of that.

1:25:421:25:46

Blood vessels are a bit like little roads inside our brilliant bodies

1:25:461:25:51

but instead of cars, it's blood that travels along them.

1:25:511:25:55

Or through them. Because blood vessels are little, tiny tubes.

1:25:551:25:59

To see how, do you want to pick up this great, big tube here.

1:25:591:26:05

What can you see happening to the coloured water inside?

1:26:051:26:10

-The water's moving around the tube.

-That's right.

1:26:101:26:13

If we imagine that the red water inside the tube is blood,

1:26:131:26:17

we can see how blood moves through the blood vessels around our body.

1:26:171:26:21

And...where do the blood vessels go to?

1:26:211:26:24

Head, arms, fingers, legs...

1:26:241:26:28

-And feet!

-And feet, that's right!

1:26:281:26:32

But why do we need blood to travel every part of our bodies?

1:26:321:26:36

Let's go somewhere to find out more.

1:26:361:26:39

-It's time to get our pulses racing!

-ALL: Yay!

1:26:391:26:42

Here we go! I can't wait to see where we'll end up today!

1:26:451:26:50

Nina said something about racing. Perhaps we're going to a sports day.

1:26:501:26:55

With funny sack races and a three-legged race.

1:26:551:26:58

And my favourite, the egg and spoon race! Ha-ha!

1:26:581:27:03

I've a feeling, it's a different kind of racing.

1:27:031:27:07

Sharpen your senses, Neurons. We're here.

1:27:071:27:10

Our senses experiment showed us that we have lots of blood vessels

1:27:101:27:14

that carry blood to every part of our bodies.

1:27:141:27:17

But why does the blood do this?

1:27:171:27:20

Our blood is made up of lots of very important things,

1:27:201:27:24

including something called red blood cells.

1:27:241:27:27

Did Nina say, "red mud smells"?

1:27:271:27:30

No, Ollie. Red blood cells.

1:27:301:27:34

Red blood cells carry something special around the body

1:27:341:27:39

and drop it off where the body needs it. A bit like a delivery driver.

1:27:391:27:44

Do you guys fancy making deliveries in these speedy go-karts?

1:27:441:27:49

-ALL: Yay!

-OK, great.

1:27:491:27:51

You will pretend to be red blood cells and you're going to deliver...

1:27:511:27:55

these balloons.

1:27:551:27:57

-So, who can tell me what's inside this balloon?

-Air.

-That's right.

1:27:571:28:02

Air contains the special thing our bodies need called oxygen.

1:28:021:28:06

Oxygen is an invisible gas and we breathe oxygen in from the air

1:28:061:28:11

and red blood cells carry it around the body

1:28:111:28:14

where it's needed to do lots of important things.

1:28:141:28:18

OK, take a balloon.

1:28:181:28:22

On your marks, get set...

1:28:221:28:26

BEEP BEEP!

1:28:261:28:28

ALL: Yay, look at them go!

1:28:321:28:35

Come on, the red blood cells! Get that oxygen moving!

1:28:351:28:39

That's an oxygen being delivered to the hand.

1:28:391:28:44

Oh, good job, red blood cell Gary.

1:28:441:28:46

Ryan picked up some more oxygen and he's taking it to the leg.

1:28:511:28:57

Fantastic work!

1:28:571:28:59

Oh, and a lovely delivery to the brain by Gary.

1:29:001:29:04

What about the feet? They haven't had any oxygen!

1:29:081:29:11

Oh, that's it!

1:29:111:29:13

Good delivery of some oxygen there by red blood cell George. Well done!

1:29:131:29:17

Fantastic! You delivered the oxygen to the different parts of the body!

1:29:281:29:34

We discovered that our blood is made up of lots of different things,

1:29:341:29:39

including lots and lots of red blood cells.

1:29:391:29:42

These have the important job of delivering oxygen around our body.

1:29:421:29:46

Other stuff is carried around our body in our blood.

1:29:461:29:50

Like water. And good things from our food which we need for energy.

1:29:501:29:55

What else does blood do? Back to the lab for a final experiment!

1:29:551:29:59

ALL: Yay!

1:29:591:30:01

As well as the red blood cells that carry oxygen,

1:30:031:30:07

our blood also contains white blood cells.

1:30:071:30:10

White blood cells helps us fight off infection.

1:30:101:30:13

-Anyone know what infection is?

-Is it when you get ill?

-It can be.

1:30:131:30:18

Infections are caused when tiny, invisible bugs called germs

1:30:181:30:23

get into our body and make us ill.

1:30:231:30:25

Germs are often found on our hands

1:30:251:30:28

which is why it's so important

1:30:281:30:30

to wash your hands before you eat and after going to the toilet.

1:30:301:30:35

But if germs do get into our bodies,

1:30:351:30:37

our white blood cells find them and destroy them.

1:30:371:30:41

For this experiment, we're going to imagine that this red paddling pool

1:30:411:30:45

is some blood and let's look at the big balloons above us.

1:30:451:30:50

We'll pretend the green balloons are nasty germs that cause infection.

1:30:501:30:56

You've got to spot any green germ balloons that get in to the pool

1:30:561:31:01

and burst them! Because you're going to be the white blood cells.

1:31:011:31:06

-Everyone ready?!

-ALL: Ready, Nina!

1:31:061:31:09

Watch our for those green germ balloons!

1:31:091:31:13

Come on, the white blood cells!

1:31:181:31:21

Oh! This is the noisiest experiment ever!

1:31:271:31:32

One left! Get it!

1:31:321:31:35

Brilliant, guys! You all did an excellent job as white blood cells.

1:31:351:31:40

You spotted the nasty green germs that shouldn't be in our body

1:31:401:31:44

and destroyed them, protecting the body from infection. Well done!

1:31:441:31:49

Your question was, "Why do we need blood in our body?"

1:31:541:31:58

I think we've answered it. We discovered that blood travels

1:31:581:32:02

from the tops of our heads to the tips of our toes

1:32:021:32:05

inside little tubes called blood vessels.

1:32:051:32:08

Our blood carries important things around the body,

1:32:081:32:12

like water and the good things from the food we eat.

1:32:121:32:16

We also found out that our red blood cells deliver the oxygen

1:32:161:32:20

that our bodies need to do many special jobs.

1:32:201:32:24

Our white blood cells destroy nasty germs that could cause infections.

1:32:241:32:29

-I hope that's answered your question.

-ALL: Thanks, Nina! Bye!

1:32:291:32:34

Bye!
