Hataraku Saibou Cells at Work

In the human body,

there are roughly 37.2 trillion cells

working vigorously around the clock.

DENDRITE

Sorry to keep you waiting!

Here is your oxygen for today.

Red blood cells are red because they contain a lot of hemoglobin.

They transport oxygen and carbon dioxide through blood circulation.

Please sign here.

Thank you.

Keep up the good work.

Of course. Thank you very much.

What's going on?

-What is this? -Oh, no. They are coming!

Run!

Endothelial cells!

ARTERIES

What a nice place.

It's not too hot, nor too cold.

There is a lot of food too.

I've decided that from now on, this will be our kingdom!

But first...

I'll get rid of all these annoying residents.

You useless contaminants!

Die!

What's with this guy?

This is White Blood Cell Neutrophil U-1146.

I've eliminated the bacteria.

White blood cells.

Getting rid of bacteria and viruses that invade the body

is their main job.

Over half of the white blood cells in our blood are neutrophils.

Listen up, we can't let any bacteria get away.

If even one of them escapes, it will be catastrophic.

So those are white blood cells.

They are so scary.

They are relentless.

He's covered in blood.

-Is there any over there? -No.

So they are the white blood cells.

Hey, what are you looking at?

Is something wrong?

No. It's just that...

Thank you so much for saving me.

I was in a bad spot.

No need to thank me.

I'm just doing my job.

But still, you're welcome.

Okay.

Is there any over there too?

Kill them all! Just kill them all!

Damn it.

Damn you, white blood cells.

Don't think that this is over.

-That was scary. -Please make way.

I need to deliver this to the Lungs Department now.

Let's see. The Lungs Department is to the right.

Hey, that's a one-way exit.

I'm sorry! I'm new here!

I got it wrong.

The Lungs Department is over there.

I got it wrong again.

Where is it?

Is it here?

Oh, my. This is the Spleen.

-What? -Are you lost?

Yes, I am. I'm sorry about that!

Don't worry about it.

Hey! This is a Lymphatic Vessel!

What are you doing?

Red blood cells can't come in! You idiot!

I got it wrong again.

I'm so sorry!

BLOOD VESSELS

There's construction going on over here.

This map is so hard to understand.

Is that so?

I guess I won't be able to get there.

Let's see. The Lungs Department.

WASTE

I don't see anyone.

There should be someone inside.

Hello? There is something I'd like to ask.

Hello? Excuse me.

Don't pretend you didn't see me, you idiot!

Die!

Antigen detected!

I found you, bastard!

Die, you germ!

That was fast. Damn you, White Blood Cell!

I won't go down that easily.

Goodbye!

Oh, no!

Bacterial capsule?

Oh, no! I lost sight of that germ!

That hurts! Don't pull on it!

Did he get away?

Hey, thank you for earlier.

What? Sure, you're welcome.

Aren't you the red blood cell I just met?

Yes. That bacteria...

He must be one of the intruders.

Damn it.

This is bad.

That guy was a Pneumococcus.

If we don't kill him quickly, he'll start dividing.

If that happens, this whole world...

Pneumococcus?

That's right.

Pneumococcus causes diseases like pneumonia.

It has a capsule and it is quite lethal.

Oh, no! I only wanted to go to the Lungs.

This is the Kidney.

I'm lost.

It's not just the Lungs that are in danger.

The bacteria are already in the blood vessel.

What? What does that mean?

Wait! Why can't I get this off me?

Pneumococcus doesn't just cause pneumonia.

It can also cause bacteremia.

The bacteria attack different organs through blood vessels.

It can even control the meninges that surrounds the brain.

It can destroy this whole world.

They act fast too.

They can invade the entire body in 24 hours.

They are that bad?

Yes, this body's immune system just happens to be weak now.

Normally, it shouldn't be a problem.

This is U-1146.

I need help to track the bacteria invader.

We're shorthanded over here too.

You just have to do it yourself.

This is...

The receptor is reacting!

He must be nearby.

Couldn't they design it better?

Hey, did that guy say anything?

Like where he was going?

What was he doing over there?

-The receptor! -Well...

He was looking at the map!

I think he was looking for the Lungs.

So he's lost too.

Yes, I think so.

Okay, then.

The Lungs?

All right.

I need to get going.

Even though the bacteria is scary,

this is my job!

The Lungs are this way.

You should come with me.

We're going to the same place.

Thank you!

Hurry up.

You need to remember how to get there.

Okay.

This area looks amazing.

Yes.

DENDRITE

-Over here. -Hello.

-Heave-ho. -Heave-ho.

Platelets.

-Oh, my! They are so cute! -Heave-ho.

-Are they called platelets? -Yes.

-Hello. -Good work!

-Hello. -Good work.

I'm sorry.

SORRY ABOUT THE DELAY. ALL THE PLATELETS

The construction ahead is still ongoing.

So we can't go through?

I'm in a rush.

Did something happen?

I'm sorry.

Actually, there has been a problem, so the construction is delayed.

The delivery workers made a big mistake.

We can't get the stuff on the top level.

We can't take it out.

-They are so cute. -They are so cute.

Let me help you guys, then.

Thank you. And you're already so busy.

No worries.

Did you see the bacteria?

He looks like this.

I don't know.

-Thank you! -Thank you!

This is really weird.

What?

Well, the receptor has been acting up.

You're right. Is it broken?

It is quite worn out, after all.

What should I do?

But nothing is wrong with it.

Announcement from the Helper T Cells.

We've been notified that there's a Pneumococcus in here.

We will be dispatching Killer T Cells.

They are elite lymphocytes that will take care of everything.

So don't worry.

This concerns our reputation.

We will kill the bacteria for everyone!
