RAT-A-TAT-TAT

0:00:550:00:57

Hello! You've caught me practising my drumming. It's so much fun.

0:00:570:01:03

I can make a slow beat.

0:01:030:01:04

RAT...A..TAT...TAT

0:01:040:01:07

And I can make a fast beat.

0:01:070:01:09

RAT-A-TAT-TAT

0:01:090:01:11

BEEPING

0:01:110:01:13

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

0:01:140:01:18

BOTH: Hi, Nina.

0:01:230:01:24

-Hello.

-We've got a question for you.

0:01:240:01:27

Why does our heart beat?

0:01:270:01:28

That's a great question. Why does our heart beat?

0:01:280:01:32

I love to make my drum beat, but our heartbeat is even more brilliant.

0:01:320:01:37

Come down to the lab and we'll do some experiments to investigate.

0:01:370:01:40

-BOTH: See you soon, Nina. Bye!

-Bye.

0:01:400:01:44

I'm going to need some help to answer this one

0:01:440:01:47

and I know just who to ask.

0:01:470:01:49

OK, Neurons, time to get to work.

0:01:490:01:51

ALL: Neurons at the ready, Nina.

0:02:080:02:10

OK. Today's question is, "Why does our heart beat?"

0:02:100:02:15

Which Neuron will be most useful to help find the answer?

0:02:150:02:18

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

0:02:180:02:21

Will it be fabulous Felix?

0:02:210:02:24

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

0:02:240:02:27

Will it be beautiful Belle?

0:02:270:02:30

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

0:02:300:02:34

Will it be lovely Luke?

0:02:340:02:36

For looking and seeing, day or night,

0:02:360:02:38

I'll help you with your sense of sight.

0:02:380:02:41

Will it be awesome Ollie?

0:02:410:02:43

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

0:02:430:02:45

my messages help your sense of smell. Or will it be baby Bud?

0:02:450:02:49

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

0:02:490:02:54

BEEPING

0:02:540:02:57

-It's all the Neurons!

-Yippee!

0:02:570:02:58

ALL: Go, Neurons, go, Neurons, go, Neurons, go, Neurons,!

0:02:580:03:05

All Neurons hip-hop happy to help, Nina!

0:03:050:03:10

Today's question is, "Why does our heart beat?"

0:03:100:03:13

Our hearts are important for every part of our brilliant bodies

0:03:130:03:16

so all of the Neurons will be helping me today.

0:03:160:03:18

Right, I need to get the lab ready before the experimenters arrive.

0:03:180:03:22

Travis likes karate and Eilidh likes meerkats.

0:03:240:03:28

But they both want to know why our heart beats,

0:03:280:03:31

so today for one day only, Travis and Eilidh become the experimenters!

0:03:310:03:36

-Hi, Guys.

-BOTH: Hi, Nina.

0:03:400:03:41

Welcome to my science lab. Come on in.

0:03:410:03:44

Now you asked why does our heart beat, which is a great question.

0:03:460:03:49

Why do you want to know?

0:03:490:03:51

Because when I hug my mummy I can hear her heart beat.

0:03:510:03:54

-And we want to know why it beats.

-Oh, I love a good hug, don't you?

0:03:540:03:59

BOTH: Yes!

0:03:590:04:01

And our heart is an important part of our brilliant body

0:04:010:04:04

so we should find out why it beats.

0:04:040:04:06

For our first experiment, we're going to use our senses.

0:04:060:04:09

ALL: Woo-hoo! A senses experiment. We're ready, Nina.

0:04:090:04:14

Can you show me where you think your heart is in your body?

0:04:140:04:17

-It's here.

-Here.

-Very good. You're right.

0:04:170:04:22

Our heart is in the middle of our chest a little bit to the left.

0:04:220:04:26

Now you're probably used to seeing pretend hearts like this one,

0:04:280:04:33

but a real heart is quite different.

0:04:330:04:36

Have a look at this model and describe it for me.

0:04:360:04:39

-It's got tubes.

-Yes.

-And they're like veins.

-Yeah, they are like veins.

0:04:390:04:45

We've got tubes going in and tubes coming out.

0:04:450:04:48

And there's also some hollow spaces inside that are called chambers.

0:04:480:04:53

As Eilidh was saying earlier, we can sometimes hear our heartbeat

0:04:530:04:57

so let's put these on.

0:04:570:04:59

Hear a heartbeat? Sounds like a job for me, Nina.

0:05:010:05:05

It certainly is, Belle. This is called a stethoscope.

0:05:050:05:08

Doctors use them to listen to our hearts beating.

0:05:080:05:12

Just press the round bit to your chest and listen.

0:05:120:05:17

BA-BOOM BA-BOOM

0:05:170:05:19

-Can you hear your heart beating?

-BOTH: Yes.

0:05:200:05:23

Wow! Nina's heartbeat sounds like a drum beating.

0:05:230:05:28

Ba-boom! Ba-boom! Ba-boom!

0:05:280:05:30

It does, Belle.

0:05:300:05:32

Let's see if we can make a noise that sounds like our heartbeat.

0:05:320:05:36

Ba-boom! Ba-boom! Ba-boom!

0:05:370:05:40

ALL: Ba-boom! Ba-boom! Ba-boom!

0:05:400:05:44

OK, so let's take our stethoscopes off. Wow!

0:05:440:05:49

So we have used our senses to see what a heart looks like.

0:05:490:05:52

And to feel and hear our heart beating.

0:05:520:05:56

But we still don't know why our heart beats.

0:05:560:05:58

So to find out I think we need to visit a place where people

0:05:580:06:01

have lots of fun.

0:06:010:06:03

Let's go, experimenters!

0:06:030:06:04

BOTH: Yeah!

0:06:040:06:05

Where do you think we're going today?

0:06:100:06:12

Nina said it's a place where people have lots of fun.

0:06:120:06:15

Maybe it's a chocolate factory! That would be lots of fun for me.

0:06:150:06:19

It doesn't look like a factory, Bud.

0:06:190:06:22

Sharpen your senses, Neurons, we're here.

0:06:220:06:25

And Nina feels very excited.

0:06:250:06:28

So, experimenters, you asked why does our heart beat.

0:06:320:06:36

To help answer that question, I've brought you to this fun park

0:06:360:06:40

to find out about the really important job our heart does.

0:06:400:06:43

Our heart helps move blood all around our brilliant bodies.

0:06:430:06:48

So it sends blood all the way up to our heads,

0:06:480:06:50

all the way down to our toes, and all around everywhere in between.

0:06:500:06:56

-Now, do you see this White Water ride?

-BOTH: Yes, Nina.

0:06:560:07:01

Well, we're going to pretend that the water moving around

0:07:010:07:05

this ride is like the blood moving around inside our bodies.

0:07:050:07:08

And unfortunately we're going to have to...

0:07:080:07:11

..have a go on the ride!

0:07:110:07:13

-BOTH: Yeah!

-Follow me!

0:07:130:07:15

SCREAMING AND LAUGHING

0:07:220:07:25

Oh, my word! Oh, dear! It feels very fa-a-a-ast!

0:07:280:07:33

SCREAMING

0:07:330:07:37

That was brilliant!

0:07:450:07:48

-Did you enjoy that, guys?

-BOTH: Yes! It was great!

0:07:480:07:52

But how does the water move around the ride?

0:07:520:07:54

That's a great question, Eilidh.

0:07:540:07:57

Finding out the answer will also tell us

0:07:570:07:59

more about why our heart beats.

0:07:590:08:01

Over there in the middle of the ride is a big machine called a pump.

0:08:010:08:05

It pushes the water round the White Water ride.

0:08:050:08:09

Our heart is our body's pump.

0:08:090:08:12

But instead of moving water,

0:08:120:08:13

the heart pumps to move blood around inside us.

0:08:130:08:16

That's what our heart is doing when it beats inside our chest.

0:08:160:08:20

-Watch.

-SHE LAUGHS

0:08:200:08:24

So, every time our heart beats it moves blood around inside us.

0:08:260:08:30

This happens again and again. Our hearts are always beating

0:08:300:08:34

and always pumping blood all the way around our bodies.

0:08:340:08:38

The blood keeps going round and round inside us all day

0:08:380:08:41

and all night.

0:08:410:08:42

Like the water goes round and round the ride.

0:08:420:08:45

That's right, Ollie. But how does this work?

0:08:450:08:48

Let's head back to the lab for one final experiment.

0:08:480:08:52

BOTH: Yes!

0:08:520:08:53

Now here is a model of the body.

0:08:560:09:00

If you squeeze this pretend heart with your hand, just like this,

0:09:000:09:04

it pumps the red water inside the tubes around the body.

0:09:040:09:07

And our real body has lots of little tubes inside it too.

0:09:100:09:14

And the heart pumps blood through them to all the places it's needed.

0:09:140:09:18

Eilidh, would you like to have a go at pumping the heart?

0:09:180:09:21

Travis, watch carefully and tell us what's happening inside the tubes.

0:09:210:09:25

Off you go, Eilidh.

0:09:250:09:27

What can you see happening, Travis?

0:09:290:09:31

The glitter is coming up

0:09:310:09:35

and the blood's coming through the tubes.

0:09:350:09:40

Well spotted.

0:09:400:09:41

Remember we're pretending that the red water inside the tubes

0:09:410:09:44

is blood inside our bodies

0:09:440:09:46

being pumped around by our hearts.

0:09:460:09:50

And the water has bits in it, glittery bits,

0:09:500:09:52

because our blood also has things in it.

0:09:520:09:55

Our blood carries important things like the oxygen we breathe in

0:09:550:10:00

and good stuff from the food we eat.

0:10:000:10:02

Remember when we listened to our hearts earlier?

0:10:020:10:05

Well, let's do that again

0:10:050:10:07

Ooh!

0:10:070:10:10

-BA-BOOM BA-BOOM

-So, listen.

0:10:110:10:14

Ba-boom! Ba-boom! Ba-boom!

0:10:160:10:19

-I can hear, "Ba-boom, ba-boom," can you?

-Yes.

-Yes.

0:10:190:10:23

Let's see if anything happens to our heartbeat

0:10:230:10:26

when we do some exercises.

0:10:260:10:27

OK, er, lets start by running on the spot.

0:10:270:10:32

Get ready and go!

0:10:330:10:35

-NINA PANTS

-Woo!

0:10:350:10:38

Come on, faster!

0:10:380:10:39

Ha-ha-ha!

0:10:390:10:41

OK, er, star jumps.

0:10:410:10:42

OK, with me.

0:10:420:10:43

One, two, three, four, five...

0:10:430:10:48

Oh, that'll do!

0:10:480:10:50

OK, now let's check our hearts again. Oh, in my ears.

0:10:500:10:54

BA-BOOM BA-BOOM

0:10:570:10:58

-Are they beating slower or faster?

-Faster.

-Faster.

-Yeah!

0:11:000:11:05

Your heart's beating MUCH faster now, Nina.

0:11:050:11:08

-Ba-boom, ba-boom. Ba-boom, ba-boom!

-Thanks, Belle.

0:11:080:11:12

So, when we run around or do any kind of exercise

0:11:120:11:15

our bodies need extra supplies of oxygen

0:11:150:11:18

to help release energy from our food,

0:11:180:11:20

so our heart beats a lot faster

0:11:200:11:22

to pump the blood around the body more quickly,

0:11:220:11:25

delivering more oxygen.

0:11:250:11:27

You asked, "Why does our heart beat?", I think we've answered it.

0:11:320:11:36

We discovered that our heart beats

0:11:360:11:38

because it's pumping blood around inside us

0:11:380:11:41

to the tops of our heats, the tips of our toes

0:11:410:11:45

and everywhere in between. That's an important job

0:11:450:11:48

because our blood carries good things that our bodies need.

0:11:480:11:52

Like oxygen we breathe and good stuff from food we eat.

0:11:520:11:55

When we exercise our bodies need more of these good things

0:11:550:11:59

so our heart has to work harder to pump the blood around inside us

0:11:590:12:03

even faster.

0:12:030:12:04

That's why we feel and hear our heart beating

0:12:040:12:07

when we've been running around being active.

0:12:070:12:10

-I hope that's answered your question.

-BOTH: Thanks, Nina. Bye.

0:12:100:12:14

Bye.

0:12:140:12:15

0:13:160:13:19

I got to hear Nina's heart beating like a drum,

0:13:190:13:22

"Ba-boom, ba-boom, ba-boom, ba-boom, ba-boom, ba-boom, ba-boom!"

0:13:220:13:27

I've had a fabby day! The White Water ride was BRILLIANT!

0:13:270:13:33

-The water moved round and round!

-Ah, it's been such a GREAT day, man.

0:13:330:13:38

Seeing how the heart pumps blood around inside us. Very cool!

0:13:380:13:43

Remember, everyone's body is different,

0:13:430:13:46

but they're all brilliant. See you soon, bye!

Nina investigates why hearts beat with the help of her five sense neurons.

Experimenters Eilidh and Travis visit Nina in her lab. They use their senses to see what a heart looks like, and they feel and hear their own hearts beating inside their chests. Next, they go to a fun park and go on a white-water ride. They discover that hearts beat because they are pumping blood around our bodies, day and night, just like the water is pumped around the ride.

Back at the lab, they find out that the heart pumps the blood around the body because blood has important things in it that the body needs, like oxygen and good stuff from the food we eat. They all do some star jumps and notice that their hearts are beating faster. Nina explains that when we do exercise, our heart beats and pumps blood around our body faster to deliver more of the important things the body needs.
