Within the human body are roughly 37.2 trillion cells,
hard at work, day in, day out, 24 hours a day, 365 days a year.
[Achoo!]
This, is inside a human.
[Achoo!]
Sneezing.
A reflex action that is a way for the body to expel foreign substances,
such as dust or viruses from the nose.
Achoo!
Achoo! Achoo!
Achoo!
Aaaaaaah…
…choooooooooooo!
[Special Episode: The Common Cold]
Listen up, maggots.
Cold season is almost on us.
Killer T cells.
Killing machines that mobilize as directed by helper T cells,
to seek out and destroy foreign bodies such as virus-infected cells, or cancer cells.
This area near the pharynx is particularly susceptible to being attacked by viruses.
Once you locate an infected cell and the order has been given, kill them on the spot.
Sir, yes sir!
Speak up, maggots!
Sir, yes sir!
I can't hear you!
Sir, yes sir!
When you locate an infected cell?
Kill it on the spot!
When the order's been given?
Kill it on the spot!
They're so freaking loud, every single day.
Yapping on about killing us cells.
Just because their job is slightly different,
they act all high and mighty.
We are the one and only mighty T cells!
We are the strongest, we've got spunk!
We are the one and only mighty T cells!
We ain't afraid of no virus punk!
- We are the one and only mighty T cells! - Guess I better get to work.
- We are the strongest, we've got spunk! - Guess I better get to work.
- We are the strongest, we've got spunk! - Unlike immune cells, I just do normal cell work.
- We are the one and only mighty T cells! - Unlike immune cells, I just do normal cell work.
Cell cycle checkpoints.
A control mechanism that monitors the progression of the cell cycle for defects.
If any defects are found, it halts the cell cycle or directs the cycle to speed up or slow down.
The cell itself is equipped with this control mechanism.
I'm so mind-numbingly bored.
Just making the same bog-standard copies every single time.
Cell division.
A phenonemon in which a single cell splits into two or more cells.
After replicating its DNA during the interphase,
the cell enters the mitosis phase, during which the cell divides.
The cycle from completing one division to the end of the next division is called the cell cycle.
The number of times a cell can divide varies depending on the type of cell.
[Spindle Fiber] Pack up mine and my copy's belongings,
[Spindle Fiber] and tie them tight with string…
[Equatorial Plane]
Same old process. When will it end?
[Copy's]
[Cell Diseases: The Threat of Viruses!]
I don't know how much longer I can take this.
Why doesn't anything interesting ever happen?
A cell?
That's a pretty sick hat he's got on.
He looks like death warmed up though.
What're you doing, man?
Alright, scrub your hands and rinse out your mouth before going on break!
Got that, knuckleheads?!
Sir, yes sir!
Ugh, it's those loudmouths from before.
Sarge, check this out.
Something came for us.
"Thanks for everything."
A present?
It may contain hazardous materials.
Maybe I should open it and s…
Y-You moron! Give me that!
Uh, I mean, how can I just let you guys expose yourselves to danger?
I'll open it.
S-Sarge…
Be careful!
It could be a present from a civilian.
I'm not saying I want it, but if they've gone to all this trouble, I might as well…
Sarge, you okay?
Sarge!
Are you hurt?
Sarge!
S-Sarge!
That's what you get for being careless, Sarge.
Jeez, now's really not the time for that!
Those punks!
Get back here!
I'm gonna tear you both limb from limb!
Stop right there, you jerks!
[Lymphatic vessel this way →]
Crap, we lost them.
Once the order to move out comes through,
they're first on my hit list!
I won't forget this.
Ah, that was scary.
You made that?
All by yourself?
"Ksha"? Is that all you can say?
You're quite an entertaining guy!
What is it?
You want to go again?
Sure! Let's have some fun!
White blood cell (neutrophil).
Their main job is to remove foreign substances such as bacteria or viruses from the body.
Nothing.
I could have sworn my receptor went off just now…
A white blood cell! That was close.
He seems to be looking for something.
N-No way.
…for us?
If immune cells are looking for us, that's bad!
"Just watch"?
Must be my imagination…
Wha…?
Huh? Damn it! Where is it?!
Hey, you there.
Oh no!
There may be an enemy in the area.
It could be dangerous, so stick with me for now.
Sir?
I can't hear you!
Um, hello?
That was fun! Let's go play some more pranks!
- Cells…! - …at Work!
Cells at Work.
Not here.
[Sugar] [Salt]
Shoot! They're back already!
I tell you, you just can't beat office work, Regulatory T Cell.
Helper T cell.
A commander cell who receives information about foreign substances in the body,
and decides on the best strategy to fight them off.
Is that so?
Regulatory T cell.
Suppresses over-active T cells and ensures abnormal immune responses do not occur.
I don't have to do any manual labour.
And I get to enjoy tea breaks.
It smells so good.
Was there an antigen in here just now?
What I want to know is, who switched the sugar with salt?!
Crap, I was too late!
Sorry, you don't have a tissue, do you?
Hey!
[No Entry]
[← Shortcut]
Nice, a shortcut.
H-Help me!
Are you okay, Miss Red Blood Cell?
I-I guess.
You know this road's under construction?
Best prank ever!
Okay, ladies. Time to head out!
Sure!
Time to get to work!
Oh my.
Goodness!
Receptor activated!
An enemy!
Find it!
Where is it?!
[Histamine]
These holy waters that cleanse the world of evil, anoint the impure soul alone.
Yet pay heed, brethren!
Improvidence is the impure mind incarnate!
Forget that,
and you may find utopia soon transforms into dystopia.
I haven't had this much fun in ages!
Man, you're really just full of good ideas for pranks.
So there are a few things you're afraid of, then.
Just not people getting angry at you.
Those immune cells are always throwing their weight around, it makes me sick.
It was fun messing with them.
But I should be getting back to work.
You want to come back to mine?
Why not? We can have some tea while we're there.
Since I became independent, all I've been doing is working on cell division, day in, day out.
So I don't really have any friends.
I'd like it if we could continue to hang out sometimes.
Actually, I've been meaning to ask, but what sort of cell are you?
That hat on your head is pretty sick.
What is it?
A hat?
You want me to have it?
Put it on? I don't know, I'm not sure…
Whoa, man.
Seriously, what the hell?
H-Help me!
Huh? More of them?!
Stop it! Don't damage my cell division device!
What, are you trying to take it over?
It can't be. You…
…were a virus-infected cell this whole time?
Just when I thought I'd finally made a friend,
it turns out he was just using me.
Quit it.
Please stop. Don't do this!
Stop it!
Stop!
Please!
Please stop!
Well, if it isn't our friend from earlier?
It's payback time, punks!
Looks like we made in time.
You, get outta here!
Looks like you don't know how we figured out you were here.
Punks.
You forgot something.
We had the RNA left all over your little present analyzed,
to identify the antigen, before getting permission to move out.
RNA (Ribonucleic acid).
Made up of the four nucleobases of adenine, guanine, cytosine, and uracil.
Fills a multitude of roles in the process of producing proteins within cells.
Some viruses use RNA as their genetic material.
Charge!
Is that all you've got?
Take that!
All you virus-infected cells, die!
Antigen located!
Time to end this.
The virus was in fact a pathogen that causes the common cold, known as a rhinovirus.
[Voyagerm 1]
Aaachooooo!
I'm so sorry, Copy! I'm so glad you're not hurt!
Tsk. Making us clean up after you, punk?!
If you had gotten infected, I'd have killed you already!
You got lucky this time.
Maybe you should take some time to read up on viruses and cells, hm?
And don't make trouble for others either!
Yes. I'm sorry.
A few days later…
Over there! Get it!
That's totally unfair!
He made it!
Nice one!
What are you maggots doing?!
- Sarge!
- Well, we were on our break, so…
Hey, why don't you join in?
W-What?
It's just, I live in the neighborhood, so I thought it'd be nice to try and get along.
You idiot! We're mean killing machines!
As if we'd get all chummy with you!
I'm a killer, you're prey.
Know your pla…
Yeah, yeah. We've heard that about a million times already, Sarge.
Don't be so uptight.
Huh? Wha…?
Wait! You maggots!
Community outreach is important too.
Come on, let's go.
Fine, but just this once. Numbskulls.
Oh my, what a monstrous home run!
Um, you know this isn't baseball, right?
Get it!
Over there!
Come on!
Why do I have to keep score?
That looks fun!
Wait, isn't this a lymphatic vessel?
