Inside every human body, there are roughly 37.2 trillion cells.
Each and every one working hard to maintain
a healthy, effective system 24 over seven.
And they all take their jobs very seriously.
Welcome to the inside of a human body.
Time delivery. I brought you your fresh batch of oxygen.
Oh, I really appreciate you coming out here.
Sorry. I know it's a bit of a squeeze.
No worries. Just doing my job.
State.
Construction. And please pardon the inconvenience.
Oh, it's a little platelet. Hello.
Hey, it's Big Sister. Red blood cell. It's not. You.
That's my.
Your carbon dioxide is being collected.
Thank you for waiting. Your oxygen is ready to retrieve.
Wow. You've really been stepping it up. Yeah.
Hey, some pie. Look at you being responsible.
Yeah. Oh, lose the fierce look. You're doing what's expected of you.
Yeah.
You're doing really well, though I admit I'm still worried.
Promise me you won't wander into any danger.
Actually, are you totally sure you're okay? I'll be fine.
Geez, You act like I'm genetically predisposed to randomly finding trouble.
Two, three.
Another day of sending 0202
all through out the body, every nook and cranny build
what is confusing And I'm lost. I'm lost.
Though we may seem hopeless. We are self-repair work for you and.
Let's get down to work. Let's get down to work every day.
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 cells 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.
Don't know who you are.
You think we're working hard? All of us together
are supporting you with all of our hearts.
No matter what kind of drive to risk our life,
we always take pride in what we do, and health comes first.
Are you working? Yes, I'm working. Working for you.
Staphylococcus aureus.
Someone else may. Honey Bunny, please.
Slushy. Slushy. Slushy.
Yes. So what?
Grab that sweet, sweet O2, baby.
That germ is closing in on him real fast.
No, we gotta help. I know, but how?
We weren't made to fight those things.
Hand it over before you make me mad.
Oh.
Oh, my gosh. I'm accidentally amazing.
Look, it's turning. I might actually survive this.
End.
You really should have been a good
girl and handed over that oxygen.
You might have lived a little longer.
Time to die, baby. Better luck in your
next life. Little red blood cell.
Uh huh. Who are you?
That hurt? Hey, who said you could cut it out?
Oh,
God.
Wow. You saved my life. Thank you so much.
Ha ha.
Cool,
Huh?
Huh? Target.
Cited.
Huh? Huh? Oh, hey, red blood cell.
Did somebody get to this antigen before
I could get hurt? Well, um, yeah.
Whoever's in that hazmat suit took out the antigen.
I don't think I've ever seen that cell before.
Oh, really? Well, that's a monocyte monocyte.
Yeah, They're another type of immune cell assigned to this blood vessel.
We work together from time to time.
Monocytes, a type of mononuclear migratory white blood cell.
Like all other immune cells, they primarily
serve the body as biological defense.
There are too many of them floating around in here,
but they do great work in phagocytosis.
Always in good hands with a monocyte. Huh?
What? Wait. Is he practicing his golf swing?
Ha ha.
Oh, it's not realized there were so many hidden migratory routes around.
I'll see you later. You're doing real good work,
so keep it up. You bet.
Greetings heading to the pulmonary alveoli. Drop in and relax some first.
Welcome. Please come on in. Heading to the pulmonary alveoli.
Oh, man. I bet that feels so good.
It's monocyte again.
Um, what's.
Oo oo oo oo oo.
Sizzle. Yum.
Splits. So we meet again.
Oh, you're all over the place today.
Wow. What are you eating? Looks delish.
You're welcome to give one a try.
Every bite is chock full of glucose.
Oh, really? I'd love to try one. Thanks so much. Looks great.
Esther.
Mm mm mm mm mm. Those were so good. I can't wait
to go back and get another. Huh? What the.
That's heavier than it looks.
Ha ha. Ha ha ha. Good afternoon, my lovely, lonely little cells.
Welcome. Your new master Staphylococcus aureus.
Staphylococcus aureus, a highly toxic antigen that commonly
resides in the skin and pores.
Should it enter the body, it can
cause a wide variety of dangerous ailments.
Among them are skin infections, food poisoning, pneumonia, meningitis and more.
It may be sudden, but I've decided
to conquer this pathetic nasal cavity. Now get to work.
Go forth my minions and round up all
of the oxygen and nutrients you see.
Target sale in this time. Still alive.
Oh. Let's kill some stuff. Red blood cell.
Get out of here. Sounds good.
Hey, at least they're here. The neutrophils will always save the day.
Filthy germ. Time to die.
So there's no escaping the white blood cells.
Where do you think you're going?
Does everybody have a coagulation factor today?
Look at that. They're the only ones left alive.
We can end this here and now.
So you're another new Staphylococcus strain, huh?
Well, each invasion is going to turn out the same.
Just like that first attempt. I could get to like it here.
Wipe out those cells.
I guess it turns
out you're the one with the flaky friends after all.
Are exterminated.
This invasion of yours ends right now.
We'll tear you apart. Nothing left but a stain.
I love how easy you think this will be.
All right, ladies, let's pull it together.
What the coming together like grapes on the vine.
How the Staphylococcus got its name. The name
Staphylococcus means grape like and is inspired
by their appearance when they cluster together.
All right then. Staphylococcus aureus. Time to close.
Um. Is this real? What is that? You neutrophils have no chance.
I've got some tricks up my sleeve.
Selves at work.
Cells at work.
Whoa. It's enormous.
See. I told you so. Today is a brand new day.
Yeah, I think you're right. Cause this
time we're going to devour you.
Time to die. Oh, that's just a.
Oh. Oh. What? How does she deflect us?
What the heck is that thing? No.
Oh, no. Perhaps you recognize my newest weapon? That's right. It's fibrin.
Fibrin. A necessary protein for the process of clotting.
The blood has a mesh or rice cake like quality.
Good, evil people. Now attach the fibrin
to the coagulation factors like this. Okay.
Keep.
That belongs to you guys, right?
Isn't that the thing you use to help close up a wound? Yeah.
Our fibrin. What the heck is she
going to do with that Fibrin.
I think I know. Stick around. Oh, no.
What is this?
Allow me to enlighten you.
Fibrin. You see, I've heard about this attack.
It's a common tactic for staphylococcus aureus
using fibrin to block immune cells from attacking her.
The name of the move is It's coagulate.
Just let me. Finish singing. You know, I was being dramatic.
The move is called Coagulase. And it's
elevated my defensive and offensive powers to
an utterly indestructible level. You're finished.
Coagulase an enzyme that brings about the
coagulation of blood by precipitating fibrin.
It allows the bacteria that produce it to utilize
fibrin as a barrier to evade white blood cell attacks.
Not a single one of your cute
little attacks can even come close to touching me.
And with this newfound strength, I can finally crush you.
The white blood cells. Okay.
Oh. Oh. Victory is such a glorious feeling. Your
world's precious defenders are buried in their work.
Such a shame they can't save you now.
No, please. Come on. White blood cell.
You have to get up. Please. She'll
kill you if you don't bite.
Please be careful, big sis. You could
get sucked out of the blood vessel.
Oh. Ha ha ha ha ha. At long last,
I can take my revenge, you nasty Neutrophil.
My sister in law invaded this body.
And you cowards put her down. And now you're going to pay.
Let's start off with something fun, shall we? Turn your lip. Lip.
So just who are you supposed to be? It's him again.
The monocytes are here. Yes.
No. That's the exterior of the blood vessel.
Okay, everyone, we're safe to take off
these hot, bulky suits. Yes, ma'am. Oh, but they The voice.
Macrophages and monocytes.
Monocytes are produced in the bone marrow and reside in the bloodstream.
But when circulating outside a blood vessel, they become macrophages.
Oh, oh. I don't know what kind of cells you are,
but you don't want to challenge me.
May we join?
It really hurts. You're much stronger than you look.
Wait, wait. No. That kind of power.
Those kinds of weapons. I just realized who you are.
You're the macrophages. Macrophages, another subdivision of white blood cells.
They capture and kill foreign substances such
as bacteria and hunt down antigens.
They also act as cleaners, tidying up dead cells and bacteria.
This is supposed to be terrifyingly strong. No.
We don't stand a chance here.
Get back here. We can still win this.
Dad, did you have a falling out with your friends? My.
My. So very heartbreaking. I'm terribly sorry
You all aren't getting along. Don't you dare patronize me.
Shall we finish this up and call
it a day? What an absolutely lovely idea.
And now to apply the finishing touch here.
Oh.
They're really strong. That was so awesome. Some.
Now, then we're all done tidying up. Simply refreshing.
All right. I got to be real.
I don't think we had a very good day today.
Definitely wouldn't call it our best. You know,
I got to say, we owe you
one macrophage. Really? Thanks for stepping in.
Who knows how bad things would have
gotten if you hadn't shown up?
Oh, come now. We could only save
the day because you gentlemen held them off.
So sorry that we arrived fashionably late.
As long as the world is safe, that's all that matters.
We're all great. Stop that. Oh, look. That's our monocyte signal.
Oh.
Of habit, I suppose. Hey. I'm
trying to sort this out in my head.
You want to say two words to say you
can hang on. How did you get inside that? No, wait.
The monocytes look so muscular, though.
I. Every girl is allowed her secrets.
Red blood cell. Let's just leave it at that.
Sometimes brutally violent. She's a nanny and a teacher. A tireless cleaner.
And a ruthless assassin.
It's no exaggeration
to say macrophages wear many hats. As you can see.
It sure is hot, huh? Platelet. Oh, I know.
Good to know, but that doesn't make it any less hot.
Next time on cells at work, heat stress.
How about some cold barley tea?
