Two, three, four. We are working for you.
Another day of sending 0202 all throughout
the body, every nook and cranny felt.
Is confusing and I'm lost. I'm lost.
Though we may seem hopeless. We are selfless work for you and.
Let's get down to work. Let's get
down to work every day and struggle.
But I gotta pull through. Oh, another day
I'm out here slicing and slicing filthy germs and viruses.
Show your ugly face won't let them get away.
I'll chase and chase some. We are
professionals for sales have worked for you. And so.
Let's get down to work. Let's get down to work.
Every day is a battlefield. You better
prepare 37 trillion and we are only two. Still, I.
So we don't know who you are.
You think we're working hard? Of us together
are supporting you with all of our hearts.
No matter what kind of strife, troubles risk our lives,
we always take pride in what we do, and health comes first.
Are you working? Yes, I'm working. Are
you working? Working. Working for you.
Erythroblasts and Myelocytes.
Inside every human body,
and every one working hard to maintain
a healthy, effective system 24 over seven.
And they all take their jobs very seriously.
Now, am I already lost again? The inside
of this body is so complex. Jeez.
Wait. What? Where the heck am I?
No way. I haven't been back in ages.
Oh. Oh. Bone marrow. This is the blood cells. Homeland
class valedictorian. Please step forward. Yes, ma'am.
Congratulations, graduate. As of this moment, you are
now a full fledged red blood cell. Truly an honor, Ms.. Macrophage.
The nucleation day. I can't believe it.
Here blood cells are born and grow
until they're ready to move into the body and fulfill their duty.
This is where I grew up. Long ago.
Confirming the birth of a precursor.
What are you gonna be?
We can make a red blood cell. She is a red head.
Sounds good to me.
Do you think
we have enough eosinophils? We just need two more.
Keep an eye out for any good ones.
It is here that the blood cells
are produced by hemopoietic stem cells.
And are then sorted by category. Red
blood cells come into this world as precursor cells.
And then mature into Erythroblasts. Macrophages nurture
them inside the bone marrow until they're fully grown.
Erythroblasts. Immature cells still in development before growing into red blood cells.
They exist inside the bone marrow.
Right now, children. Is everyone all settled in?
I'm macrophage here to ensure you all grow up healthy.
I'll be looking after you until it's
time to Anucleate. So let's all do.
If we work together, I'm sure you
will become outstanding red blood cells.
Our first lesson is to memorize this map.
All right. Are you ready for your first practice delivery run? Yes.
Yeah. Let's deliver this oxygen. Ready? Go.
All right. Time to do my. Best.
Good luck out there. You can do it.
It's a dead end. It's this way.
Oh, wait. No. Maybe that way. But then this way, it's.
This way. And it's still that way.
Which way? Which way? Oh, Miss Macrophage.
The girl got so large that she got
dizzy and fell over. Oh, no, sweetheart.
There, there. Don't cry. You'll be fine.
You'll know all the routes soon enough. No need to worry.
The blood vessel can be a dangerous place sometimes now and then.
You just might run into some big, scary bacteria.
So today we're going to practice running
away and searching for safety. Okay.
As soon as you see a bacterium
hurry around the closest corner you can
find and hide until it's safe.
And we have a guest to help us learn.
Mr. Neutrophil will play the role of the bacterium.
Hey, kids. This girl's gonna get lost
in all eaten up by a germ.
Please don't say that. But now, kids,
it's important to pay attention when your
teacher is talking. Sorry, I have a question.
What would happen if I do end
up getting lost? You don't need to worry.
That's right. We're perfectly safe here. Since you're still children,
it's impossible for you to leave the bone marrow.
And as long as you stay inside,
it won't take us any time at all to find you.
Just concentrate hard and you won't get lost.
If you're feeling scared, we can run from the bacterium together.
Really? Thanks so much. All right. Is
everyone ready? Okay, here we go.
No, Sorry. Did you want me to take
the lead here? If you please.
Well, King bacterium is getting hungry. Who
here wants to get gobbled up?
Where do you read? Let's just get going.
I sure do hope you all manage to hide.
Come now don't let that scary that.
You. Oh, no. Where'd she get to? Somebody help me, please.
What is this place? Did I go and get lost again?
That bacterium is scary. I wasn't looking where I was. Running.
They can't. I'm never gonna learn how
to become a good red blood cell.
Sorry for the wait. Here's your oxygen.
Thank you, as always. Of course. Well, you take care.
I need a package over here. Roger that.
Make that one for me, too. I'm on it.
Wow. They're so professional. They look so cool.
I wonder, are all red blood cells as cool as they are?
If I work hard enough, maybe I can
turn out to be like them someday.
Hey, little one. What are you doing out here all on your own?
Oh, hey, teacher. Just now I saw all the.
So you're alone. This is so delightfully easy.
You're an erythroblast, right? A little red blood cell in the making.
When did you put on that new costume teacher? It looks so.
Your teacher will. I suppose that's not
much of a stretch after all.
I am certainly going to teach you the lesson of a lifetime.
Lesson one This is no costume. I
am a genuine, real deal. Pseudomonas.
Oh, so you want me to chase you? Yes.
Erythroblasts are not permitted to leave the bone marrow. Thank you.
Why not?
Bacterium like me can survive without stealing nutrients or oxygen.
So why would I go through the hassle of invading this?
Care to take a guess why? Because
I just love torturing helpless little blood cells. Of course.
Poor thing. You want this to be over?
Ask nicely and I'll go ahead and finish you.
This is heartbreaking. After all, you're only
a child, and it's just tragic.
You'll never grow up. But that's what fate has in store, Castell'azzara.
No, I don't want to die. I want to grow up. Brave.
Yea, I
am not. Those cool red. Help me through all this. And so can
I. You wretched, beastly little brats.
Playtime is over. Now die. Stay back.
Filthy germ. I'm not going to let
you hurt an innocent red blood cell. Not my body.
Got the target sighted. Who are you?
I'm not going to waste another breath on a germ.
Oh, yeah? Well, I'm going to wager
that you're just a Milo size,
a little white blood cell in training.
Do you really think you can kill me?
I don't think it. I know I can.
Oh, aren't you terrified? Star jam. Prepare to die.
No. My weapon. You've got some spirit, haven't you?
Is every branded here such a pain?
I'm sure one day the two of you
would have made very impressive sales.
Too bad you won't live long enough to see it happen.
Yeah.
I'm having such a blast. It looks
like I get to quash two promising little futures today.
Little known fact. There's nothing more fun
than tormenting the weak and the helpless.
Oh, please. You have to get up
now. Let's talk. Lucky for you, I have
a soft spot for kids with courage.
So if you hand over that erythroblast without a fight,
I'll spare your life and let you walk away.
How's that sound, little boy?
You monster. You really think I'd do? Seriously.
White blood cells never surrender.
Even if we have to sacrifice our lives.
We will protect innocent itself. Watch out,
cause I'm going to be a great white blood cell.
Bad choice. You stay away from them.
I.
It's all right, you two. You're okay.
Thank goodness. We were so worried.
Ha, ha. Rough day, huh?
Come on, let's clean up those scrapes.
Before you go, Neutrophil. Thank you for all of your help.
Wait. Don't go.
Thank you for rescuing me. You are really brave. Why
will I ever see you again?
I don't know.
I hope. But. Although. One day when
we're both grown up and working hard,
Maybe we'll see each other then. See you.
I've been so busy since
I started working that I forgot all about that.
But being here brought it rushing back.
Okay, time to deliver this oxygen.
Oh, geez. I am so sorry. I can't believe I did that.
Are you okay? Please be okay. I'm fine.
I wasn't looking where I was going.
Uh, is that you? White blood cell.
It totally is. Guess so. We see each other a lot.
Here, I got you a fresh cup of tea.
You're lost again, aren't you? Yeah, thought so.
Come on. I'll walk with you. I'm free at the moment.
Thank you so much. You're amazing. Yay!
Guess I'm always getting bailed out by white blood cells.
That boy who saved me. I wonder if he's all grown up now.
It was so long ago, I can barely remember his face.
There's no way it could be. Hmm.
You okay? Sorry. Of course it isn't.
There's trillions of cells. That would be too
much of a coincidence, right?
Cells at work.
Thank you for showing me the way.
Guess that's another one I owe ya.
See ya. It's been so nice and quiet lately.
Yeah, We haven't had any incidents.
That's good. T, if only a piece like this could last forever.
It's fine. Get away. Please. No. Somebody help me.
What happened to him? That's one weird looking cell, huh?
Gotta admit, it's been a minute since
I've seen you take down a rogue cell Neutrophil.
What are you doing here? Wanted to thank you.
I appreciate you looking out for naive.
Oh, he's looking rough. You think maybe
he got infected with a virus? Yeah, most likely.
It's hard to stomach having to take
down our own cells like this. You said it.
Now, then, I better go and check
the corpse into custody. Hey, uh,
cell related troubles my department. So you can leave this to me.
All you gotta do is focus on killing that bacteria.
What is that supposed to mean? Dealing
with cell trouble is part of my job, too. Uh,
you gotta share the wealth, then. Honestly, White blood cell.
I'm dying of boredom over here.
Hey, what the. And KSL natural killer cells.
A type of white blood cell that patrols the body.
They seek and destroy viruses and cancer cells.
Sorry about the landing there. I needed a cushion.
And you're full of hot air, you jerk. What the heck was that?
Just as I thought. No ordinary virus got Ahold of this guy.
This one proliferates faster than anything we've seen. What?
I'm sure his buddies are still hanging around,
and I got a feeling that cell will lead me right to him.
Let's have a little chat. This guy ain't the only one, is he?
No, I don't think so. There were
a bunch more of them over where I live.
What? In the cell system? Why didn't you say anything sooner?
That's kind of what I've been trying to tell you guys.
Are you kidding? Let's go, then.
Slow it down, blondie. You see, work
has been a little boring for me lately.
I could use a bit of fun,
so I'm going to play the jurisdiction card. What?
And one other thing. You stay here like good boys.
Last thing I want is one of you getting in my way.
This one is all for me. Wait, What?
Just who do you think you are?
Oops. Hand slipped. Sorry about that. Don't worry,
boys. I can handle this one. Hey there, killer. T you good?
And then I hear that my budget. Here you go.
Look at that. Funny how easy a hand can slip.
Well, I'd hate to see you catch a cold.
You better head home. Maybe put on a pot of tea, little lady.
How crazy. My hand slipped again. Sorry.
My foot slipped somehow. Well, what do you know? My elbow slipped.
So sorry. Elbows do not slip. Admit
you did that one on purpose.
Oh, I will if you will. Buttmunch.
I'm gonna kill you. Kill you?
Go ahead. I could use a good laugh.
Is this normal for them? What do you expect from immunity cells,
huh? Not exactly buddies, are they? No, they are not.
Maybe you and I should just go
on ahead. And by the way, Cell, I just wanted you to know you
don't have to come the whole way, all right? Huh?
I may have to take the lives of cells,
and there's a good chance those cells
will be your friends and your neighbors.
You shouldn't see that. Really? No, I'll be fine.
Really. I can take you all the way there.
It's the least I can do to help save the world.
And I owe you. I mean, you did kind of just save my life.
Thank you for doing that. It's the first
time someone has ever come to my rescue.
So trust me, I totally understand. There's
nothing we can do about the way things are.
The cost of peace is high. Sometimes
it's the people you love most
and really you're just trying to do your job. I get that.
That's kind of you to say. I never
would have guessed there were immunity cells
sensitive to the loss of others.
Well, we do our best. But do me a favor, okay?
Try not to mention that in front of Killer T.
Get some. I'm not done yet.
Hey, kid, I thought you said there were other cells here.
There's no sign of anybody. Oldest virus trick in the book.
I'm sure they're just keeping quiet and hiding
around here somewhere. We'll find them.
It's deserted.
This place is bad news. Let's call this in to HQ. And then
the four of us can patrol the area with her.
Yeah. Fat chance of that. Looks like we got to split up.
I've got dibs on the little guy.
Good idea. Wouldn't want to get yourself
lost in the creepy abandoned building.
Hey, come on. No fighting. I'm not fighting.
This is a freaking rejection reaction. How
can I do my job if I'm
teamed up with that freaking lunatic? Good thing you're not sorry.
White blood cell. Looks like you're stuck with babysitting.
Hey, let's focus on the job at hand, all right?
I can't believe she took off with that cell.
Why won't you just listen to me?
You got to be compatible with the teammate. Compatible, huh?
That idiot never shuts up, does he? Now, as for you and me.
I think we've held off long enough.
You ready to get started? What?
It took a while, but we're finally alone.
I'm plenty happy to dance if you want a partner.
But if you want to die wearing
that disguise, feel free to stay put.
But I think it's time for the truth.
Guess you caught me. Keep
Uh oh. Looks like I'm under siege from bad vibes.
Now show me the monster you really are.
This is no viral infection. Time to die.
What happened to that cell that was with us?
This doesn't feel right. Finally got you all together.
