Stroke£¡ Stroke£¡
You're looking good, Ms Frizzle£¡
Stroke£¡ Stroke£¡
Come on, come on£¡
Stroke.
Yes£¡ You're two seconds up on yesterday£¡
Yay, team£¡£¡£¡
WHOAAA£¡£¡£¡ Ptooi£¡
Four more minutes, Ms Frizzle£¡
Don't you think you better go easy on her, Ralphie?
Can't£¡ All great athletes have to train to build up their muscles£¡
lf Ms Frizzle wants to win the Teacherathalon, she's got to have muscles£¡
Phew. But muscles aren't everything, Ralphie£¡
WHA-HOOOOO...£¡£¡£¡
How DOES she do that???
Ms Frizzle will need the strongest muscles she can get
to stand a chance against that other teacher.
Keesha's right. l heard Mr. Sinew's so big, even his muscles have muscles£¡
How'ya feeling, Ms Frizzle?
Ah£¡ Fit as a fiddle, Tim£¡
Wish l could say the same. My heart is pounding like crazy£¡
As my vain old Aunt Artery used to say...
''Without that pump, you're going to slump£¡''
You're telling me...keeping up with you ...is harder than l thought.
l'm out of breath, too£¡ l can't get enough air£¡
And the same goes for the Bus£¡
Good idea Liz£¡
Stroke£¡ Stroke£¡ Stroke£¡ Ah, can't you guys pump any faster?
We're going to be late for the Teacherathalon£¡
Almost there, Ralphie. Just a little more air£¡
l could use some air, too£¡
Of course you could, Arnold£¡
That's what happens when you hustle those muscles£¡
That's why your lungs are part of the team£¡
Team? What team?
lf you ask me, there's only one team around here.
Janet£¡
Me and Mr. Sinew...
Say hello to your competition£¡ The original physed teacher extraordinaire£¡£¡
Hello, Ms Frizzle.
Nice to see you, Mr. Sinew.
May the fittest teacher win£¡
My-oh-my, you must ruin a lot of shirts that way.
You bet. Come on, Mr. Sinew - let's jog easy back to the school and...
...Oh well, it's hard to keep those big muscles down...
How is Ms Frizzle ever going to beat that... that mountain of muscle?
You know, class, there's more to winning than muscles.
Muscles are just part of the team.
What team, Ms Frizzle? lt's one on one - you against that hulk.
We'll see about that...
Hellooooooo, WalkeRVille£¡
Welcome to the final round of this year's Teacherathalon between Ms Valerie Frizzle...
...and Mr. Garth Sinewwww!
Thank you Janet. We got the message.
Now, the teacher who wins two out of the three events
takes home the prestigious 'Totally Bodacious Athlete's trophy£¡
Okay, it's time for the first event of the Teacherathalon£º
the row-row-row-your-boat-to-the -end-of-the-lake-first-one-there-wins event£¡
lt's time, Ms Frizzle. Good luck.
Good luck to you, too, Mr. Sinew£¡
Teachers to your boats£¡
Sinew rules£¡
Up with the Friz£¡
Um... can you give me a hand here Mr. Sinew?
Certainly£¡
Whoa£¡ Did you see that??£¡
Something tells me we could be in trouble...
Teachers ready...
...get set...ROW£¡
Go Ms Frizzle£¡ Row£¡
Stroke£¡
We're winning£¡
What was that?£¡?
Hiccups Ralphie£¡
Oh no£¡ What're we gonna Ms uh... MS FRlZZLE...
Look£¡ lt's a ardeaherodias£¡
Really? Where?
Boo£¡
Did you say something?
OH£¡ Just hold your breath.
Whatever you say, Ralphie...
Sorry, Ms Frizzle - someone's got... to win... and... it's going...to...be... me£¡
BYE BYE£¡
And the winner of the first event is Mr. Garth Sinew£¡
Oh no£¡£¡£¡£¡
What happened Ms Frizzle?
You were winning£¡£¡
Well... for some reason, my muscles gave out.
Excuse me£¡
But we were doing just fine... until you got the hiccups and held your breath.
Well, that's the problem£¡
Everyone - except Coach Ralphie - knows you can't row if you're holding your breath£¡
Why not? What's breathing got to do with how your muscles work?
Ah, now there's an air-udite question£¡
Attention, attention competitors.
Five minutes till the next event£¡ Five minutes£¡
Ahh...to the Bus£¡
To the Bus?£¡?
Single file please£¡
Do we really have time for this?
lt's okay, Ralphie. We all need a little breather. Hit it, Liz£¡
What is that??£¡?
This is the Supreme Team Analyzer Manifesting lnternal Networks Automatically -
or STAMlNA for short.
That is so cool£¡
Wow£¡ l see your heart, Ms Frizzle£¡
You don't miss a beat, do you, Tim?
The red liquid must be your blood flowing£¡
But what are these big sacs next to the heart?
Oh, those are my lungs£¡ First stop on the Air Express£¡
Air Express? What is she talking about??
Look£¡ Ms. Frizzle's blood goes from the heart to the lungs...
and then back to the heart.. and then to everywhere£¡
The heart pumps the blood twice£¡
Forget the blood - it's her muscles l want to know about£¡
That's what she needs to win the Teacherathalon£¡
Muscles are certainly part of the team, so let's go out on a limb...
Oh, look at those leg muscles£¡
They look good and strong to me£¡
So what does holding your breath have to do with how your muscles work?
Ralphie, l think you need a closer look...
Oh no - tell me she didn't say that£¡
Attention, attention all competitors. Event number two is about to begin.
Mr. Sinew and Ms Frizzle, please report to the starting line in three minutes.
l'll take my closer look another time, Ms Frizzle.
Ralphie's right£¡ We have to get back to the track£¡
Huh, not to worry Arnold.
You have lots of time to find out what air and muscles have to do with each other.
We do??£¡?
Oh yes, and you're coming with me Tim - this way please£¡
Let us know what you find out£¡
ls it just me or are we going on a field trip?
Come on Bus - do your stuff£¡
Where'd the bus go?
lt's right in the palm of my hand.
OK class time to take chances, make mistakes, get messy£¡£¡ And breathe deep.
Ms Frizzle - where are we going??
ln there with the air£¡ Hit it Liz£¡
This is typical.
The next event is about to start any minute and what are we doing?
WE'RE DRlVlNG lNTO MS FRlZZLE'S NOSE£¡£¡£¡
Air oh air has my little class gone£¡
WHAA-HOOO£¡£¡£¡
Air oh air can they be?
We're heading toward your lungs£¡
Attention, attention, 1 45 seconds to event number 2.
Get your popcorn now.
Oh, better warm up£¡£¡ One... two...
Hey you guys£¡ Can you hear me?
We hear you£¡ WHAT lS GOlNG ON??
We're getting ready to start. Where are you?
We're right here, we're just entering Ms Frizzle's left lung£¡£¡
Then step on it£¡
Excuse me?£¡?
l mean hurry£¡£¡£¡
We're in Ms Frizzle's lungs.
Yeah - you're being frizzled big time£¡
So all this noise we're hearing must be the sound of her breathing air£¡
But these tubes are getting smaller and smaller.
Oh no£¡ We're not gonna fit£¡
But why now? How am l going to coach her to victory from inside her lungs?£¡?
Way to go, Liz£¡
lncredible£¡ l always wondered what Ms. Frizzle was like deep down inside.
Time's up£¡ We win£¡
She'll be back.
Well, l'm going to complain. l'm good at that.
Well, l guess everybody's good at something...
May day£¡ May day£¡ Where are you guys?
Janet's gonna disqualify us£¡£¡
Have you guys figured out what breathing has to do with muscles yet?
We're working on it. We're following the air as she breathes it through her lungs.
Who knew your lungs were made up of so many tiny sacs.
Whoaf£¡
Looks like the air stops here.
NOW what'll we do??
Well as my Uncle Ether always says, when you hit the ground, take a look around.
Well, the air's still moving as she breaths, but where's it going?
Wait a second.
This looks familiar, kind of like when we were in your bloodstream, remember?
You mean when you followed my blood cells all around my body?
What's that got to do with air?
Plenty Ralphie£¡ Watch.
When the air hits the purple blood cells, they suck it up and they turn bright red.
Look£¡ lt happens when she breathes in£¡
l guess the air doesn't stop here after all.
But where does it go from here?
We've got to check this out£¡ Follow that air£¡
Nice one, Liz£¡ We're in the blood stream£¡
But where is it taking us?
What's that noise?
Ooh, you're getting to the heart of the matter now class.
We're going right into her heart£¡
Now what??£¡?
l don't know, the heart is a pump.
Get ready to get squeezed outta here.
AAAAAAAH..!
One and two and one and two...
Attention Ms Frizzle£¡
lf you're not at the starting line in one minute, you're disqualified£¡
Go away, Janet£¡
Did she say 'disqualified'??£¡
This way Tim.
And they're off£¡
Mr. Sinew he's our guy, he's gonna win, easy as pie.
l'm gonna... win£¡ l've... got... the muscles£¡
But... l've got... the heart... and the lungs£¡
Sure feels good to be back in the blood stream, huh Ralphie?
But Ms Frizzle's is flowing a lot faster than your's did Ralphie£¡
Well, what do you want? l was resting, not racing against the credible hulk£¡£¡£¡
They're at the half-way point. No telling who's going to win this one£¡
l've... got... the edge£¡
But l've... got... the TEAM£¡£¡£¡
We're moving closer and closer to her leg.
Yah, but where are the muscles?
l think we need to hang a left£¡£¡
What are all those red bands out there?
According to my research, that is the muscle fibre.
Muscle fiber£¡ Stop the bus£¡£¡ Hey, look at that£¡
The red blood cells are giving that white stuff to the muscles.
And then turning back to purple.
l gotta go check this out£¡£¡
lt's almost as if the muscles are breathing in the white stuff.
And breathing out the dark stuff. Phoebe£¡ That's it£¡
Those red blood cells are bringing air to the muscles.
Hey guys, l got it, air has oxygen£¡ That must be what the white stuff is. Ooh.
According to my research that's the part of the air our bodies use to live.
So, the lungs breathe in air...
...the blood cells carry the oxygen...
...the heart pumps the blood...
To our muscles which use the oxygen£¡
So that's the team Ms Frizzle keeps talking about.
Lungs, blood, heart and muscles. They're all working together£¡
They're the oxygen team£¡
They work together to pull oxygen into the body, pump it into the muscles,
use the oxygen up, and carry away the used up stuff£¡
What a team£¡
So when Ms Frizzle held her breath, her muscles didn't get the oxygen they needed£¡
She didn't have a muscle problem - she had...
...an oxygen problem£¡
l'm ... going... to... win£¡
Not if l... get... there... first£¡
Ralphie? l think maybe you better come look at this£¡
This doesn't look too good to me...
Man, that grey stufts showing up all over.
And there's less oxygen going into the muscles.
l think we've got another oxygen problem here£¡
Hello Tim, we can't keep up this pace.
The muscles aren't getting all the oxygen they need£¡
lt's going to be rrrreally close...£¡
You're good, Ms Frizzle... but...not... as... good... as me£¡
Not... as... good... as... l, Mr. Sinew£¡
And the winner is...MS FRlZZLLLLLLLE£¡
The score is even - one event apiece£¡
She did it£¡£¡ Ms Frizzle won the race£¡
Wha...hooOOOOPS£¡ l... think... l'm going... to fall... down£¡
Are you all right, Ms Frizzle?
l must have overdone it a little. My muscles need a few minutes to recover.
l'm sorry, but you don't have a few minutes. Do you give up?
No way£¡
Get better quick, Ms Frizzle. l would hate to win this way.
But if that's the hand you're dealt...
Janet£¡
What's going on in there, you guys?
Without enough oxygen, Ms Frizzle's leg muscles stopped working£¡
They're as limp as overdone spaghetti£¡
But there's no sauce, just this yucky ooze.
Excellent obseRVation, class£¡ That yucky ooze is lactic acid.
lt's what muscles make when they have to work without enough oxygen.
That's what happens when you take your team to the wall.
Ah, but not to worry - with enough time to rest, my blood will clear out the waste,
bring in more oxygen, and l'll be ready to go again£¡
Yes to worry£¡ The next event is about to start£¡
l know£¡ Ooh, this is working out better than l thought£¡
So here's the story -- This yucky ooze tells us her muscles don't have enough oxygen.
But there's no time for her blood to do the job.
So, we've got to get more oxygen to her muscles - NOW£¡
We'll have to go back up to the lungs to get some£¡
There's not enough time£¡
And we've got to clean this ooze up, too£¡
Great idea Liz, let's get mopping£¡
The ooze is disappearing - but now what?
Her muscles still need oxygen£¡
l know... We need to get more oxygen to these muscles - and fast£¡
We need new air£¡
l've got it£¡ The bus tires have new air - we pumped it in there, remember?£¡
We can use that£¡
All right, guys, let'em blow£¡
lt's working£¡
The muscles are starting to move again£¡
How's your leg, Ms Frizzle?
Tell everyone my muscle feels as good as new.
Now, my heart, lungs and blood will do the rest.
Mission accomplished, guys£¡ The team's back in shape£¡
You can come out now£¡
Let's go£¡ l've got to see the look on Janet's face when Ms Frizzle wins that trophy£¡
With the contestants tied one win each,
the winner of the tire-step-backstroke-stair-climb event
will be the winner of this year's Teacherathalon£¡
Come on Mr. Sinew, 233, 234, 235...
Ms Frizzle you're looking great£¡
You guys in the windpipe yet?
Are you kidding?£¡ We're still going up her leg£¡
You're still going up her leg??£¡ But don't you want to see this race??
You know, Tim, when this is over, you better take a long vacation. l think you've lost it£¡
Attention, attention£¡
This is the movement you've all been waiting for, the final event,
the tie breaking, the trophy winning, the...
Teachers, are you ready?
On your mark£¡ Get set£¡ Go£¡
The race is on£¡ They're off and stepping£¡
GO£¡ SWlM£¡
Close, Ms Frizzle... but no cigar£¡
Don't you know... that smoking... is bad for your... health?
lt's anybody's race£¡ They're stride for stride£¡
Go, me£¡ Go£¡
Go, team£¡ Go£¡
Hang on gang£¡ We're in the lungs again and we're almost out£¡
Come on, Ms Frizzle. Take chances ...get messy...and GET US OUT OF HERE£¡
We're almost out£¡ There's her vocal cords.
lt's really close£¡ The winner of this year's Teacherathalon iiiiis...
...MS FRlZZZZZZLLLLLLLLLLE£¡£¡£¡
WAHOOOOOO...£¡£¡£¡
FRlZ-UL£¡ FRlZ-UL£¡ FRlZ-UL£¡
FRlZZLE£¡ FRlZZLE£¡ FRlZZLE£¡
l just don't get it£¡ How could your puny little teacher win against my muscle man?
Well, Janet, he was up against an entire team -- Ms Frizzle's lungs took in oxygen...
...then her blood carried it...
... her heart pumped the blood...
...to her muscles which used the oxygen to do the work£¡
And then, of course, there was us - we were on the team, too£¡
Whaoahh. You're a good champion, Valerie. Next time l'll train harder.
Well, there'll be no next time for me, Garth. l'm retiring.
As l always say, 'air today - gone tomorrow'£¡
And the same goes for your shirts£¡
You're right, Liz.
lf l want to win next year, l'll have to do more aerobics to keep my lungs, heart,
muscles in tip-top shape.
Hello, Magic School Bus?
Uh, no, this is Mr. Sinew.
Okay, you'll do. How does exercise get you in shape anyway?
Well, it helps your lung tissues stretch further so you can take in more air...
And it strengthens all your muscles...
... including your heart. That's the most important muscle in your body, you know.
l guess l better get exercising£¡
Good idea£¡ Bye£¡
Now what?
So, l know that white stuff was oxygen, but what was the dark stuff?
The dark stuff was carbon dioxide that the muscles give off.
The blood carries it back to the lungs where we breathe it out.
Carbon dioxide is the second half of the breathing story.
But we didn't have time to show it all.
Can you really see all that stuff the way you showed?
No.
Oxygen and carbon dioxide are invisible gasses, and lactic acid is a colorless liquid.
Red blood cells turn bright red when oxygen joins the cells,
and they turn purple when oxygen leaves the cells. Whoa£¡
Hey, are you okay?
Never felt better, thanks£¡ Bye£¡
Whew£¡ Not rowing£¡
l'm with Janet -
how could someone like Ms Frizzle beat a mountain of muscle like Mr. Sinew?
Having big muscles doesn't necessarily mean you're in good shape.
What's important is teamwork.
Your heart and lungs have to work together
to deliver as much oxygen to the muscles as possible.
That's right. And blood carries food as well as oxygen, doesn't it?
That it does... Whoa. Bye£¡
That's it, Liz. l've gotta rest.
Aren't you tired?
You've got some kind of heart-lung-blood and muscle team Liz...
And the same kind of shirts as me...£¡
