00:00Life, life, life, life, life, life, life
00:06And here is life, beautiful life, eager to blossom.
00:13The world invites us to new dawns.
00:19He gives us a bright future.
00:23And the sun that dazzles us
00:27The fresh air entices us
00:30It fills us with joy and life
00:34Life, life, life, life, life, life, life
00:41Life, life, life, life, life
01:09Since the beginning of his existence, man has had to face danger.
01:23But today, large animals are no longer man's most dangerous enemies.
01:27nor even the smaller ones, for that matter.
01:30Infinitely smaller, these are our worst enemies. Bacteria, viruses, poisons, toxins. Here are some of the ones we need to deal with.
01:38combat.
01:39If it settles in the stomach, it can cause a nasty case of gastritis.
01:43It's easy to get in through the nose. There's a bad cold, that's all there is to it.
01:46For real.
01:47A minor allergy, believe me, there's nothing like it to annoy the world.
01:51At least a bad case of the flu. How about a really bad case of the flu with a high fever?
01:56?
01:57Personally, I think food poisoning is something to consider. It's easy to get infected, it spreads without any problem.
02:03The defenses are ineffective.
02:06Thankfully we are here, we, the body's sentinels: B lymphocytes, T lymphocytes, polymorphonuclear leukocytes, macrophages.
02:13and many others.
02:21We are also simply called white blood cells.
02:24There are about a million billion of us in a human body, you see.
02:29Two hundred thousand times more inhabitants than there are on Earth.
02:32In a single body to watch over him, to protect him from everything foreign to him, everything
02:36which is harmful to him.
02:38Most of us are born in the bone marrow.
02:47Every day, 15 billion white blood cells are born into the world.
02:53For men, this represents the value of three teaspoons.
03:12Look at the big one coming.
03:14You'll see.
03:21It's high time we sent you to school to teach you how to behave.
03:26Yes, but they are old enough to learn.
03:43Come on kids, games are over.
03:45Gathering in groups of four.
03:49We're going to school.
03:55What is school?
03:58What do we do there?
04:00Are we going to have fun?
04:03And what's it called?
04:05The school for white blood cells is the thymus.
04:08You already have a few hours of existence.
04:11And it's time for you to learn a trade.
04:14What is the thymus and where is it located?
04:16What kind of job?
04:17The thymus, well, it's the organ that forms our body's defenses.
04:23And your job will be the most beautiful.
04:25Learning to distinguish our friends from our enemies.
04:29To fight and destroy them.
04:32Your life will be exciting.
04:35Exciting and very full.
04:37Even if it doesn't last long, you'll see.
04:39And now, let's not waste any more time talking.
04:42Alright, let's go!
04:47We will now get to know better those who will be your enemies.
04:52Note that it is very important to be able to spot them at first glance.
04:58Here are viruses of all kinds.
05:00They need cells from the human body to multiply.
05:04So they invade and destroy them.
05:06They cause diseases such as the flu, measles, mumps, polio and many others.
05:13See, filmed by our war correspondents, their method of operation.
05:24There was also smallpox.
05:26But thanks to vaccination campaigns, we were able to prepare troops who, battle-hardened, eliminated this dangerous enemy.
05:51Hey, wake up! It's really important to know our enemies.
05:55Yes, bacteria.
05:56They settle in favorable corners to proliferate.
05:59They cause whooping cough, diphtheria, tuberculosis, meningitis and many other diseases.
06:03Ah, here come the staphylococci or coxies.
06:06They are formidable because they have learned to resist many drugs.
06:11They must be destroyed without mercy.
06:30But listen to what he says.
06:32Otherwise, you won't be able to recognize our enemies.
06:34But there are also beneficial bacteria, friends, that the body needs.
06:39Millions of these help to digest food and produce vitamins.
06:43Of course, you should never attack them.
06:47God and Nopsy, will you come among us, I pray?
06:51At your service, Colonel.
06:57Ah!
06:58Ah!
06:59Ah!
07:01Ah!
07:02Ah!
07:03Ah!
07:03Ah!
07:03Ah!
07:06Lieutenant Psy, who is a brilliant officer in our police force,
07:10will now introduce you to some of your friends,
07:13of your travel companions.
07:16During your travels,
07:18You will sometimes be required to enter blood vessels.
07:21For us, lymphocytes or white blood cells, it's an easy thing.
07:25We are indeed very malleable.
07:33Our friends in blood plasma: proteins, lipids or fats, sugars, salts, minerals, vitamins and many others.
07:41And you know, they make up more than half of the blood.
07:44Almost all of these are nutrients for the body.
07:47And the body constantly needs a wide variety of substances, because it is in a continuous state of renewal.
07:52The other half of the blood consists of oxygen carriers, the fuel for the engines of cells.
07:58And these carriers, those that give blood its color, are our friends, the red blood cells.
08:05And the tiny platelets that repair wounds and regulate blood flow, they are also our friends.
08:11This entire, kind population is completely defenseless.
08:20And it is one of our noble functions to defend all these people against our enemies.
08:29You understand that it's important to know who to attack and never make a mistake.
08:34This has already happened as a result of poor upbringing and it risks causing serious damage to the body.
08:40So be very careful.
08:51I'm calling Captain Pierrot, I'm calling Captain Pierrot.
08:56At your orders, Colonel.
08:58Come join us, Captain.
09:13I present to you an ace of our nuclear police, Captain Pierrot.
09:19The captain will tell you about your fellow fighters.
09:22As the colonel and the psychiatrist explained, our task is to fight against everything that is
09:27foreign to the organism.
09:29The intruders, the invaders.
09:34We, the white blood cells, come in various species.
09:38The type B infocyte, we fight the enemy by sending our para-antibodies to it.
09:44We are enlarging 2000 per second.
09:472000 per second, can you believe it?
09:51All of these are designed for a single type of enemy.
09:55Sir, sir, I mean Captain, why only one type of enemy?
10:02Because it was through contact with that enemy that we developed our defenses.
10:06And it would not recognize any other enemies.
10:11This is the metro antibody chief.
10:12What information do you have for yourself, Captain?
10:14You explain.
10:15Oh yes ?
10:18Well, we are specific to the type C influenza virus.
10:22But we have specialists in all fields.
10:25And I have lookalikes, they're incredibly realistic, you'll see.
10:28Well, my dear, you will have to excuse me.
10:30Now we have visitors too.
10:31Duty calls.
10:33But not only duty.
10:35Pleasure too.
10:36The pleasure of doing one's duty.
10:37Do you understand?
10:43Sir, Captain
10:44But if there's only one police ship and many enemies, what do you do?
10:48Excellent question.
10:50First, we are never alone for long, because others come running.
10:54And then there is mitosis, the splitting.
11:01Ah, so how do they do that?
11:08We also have T-units among us, killer units.
11:12Their mode of action is different.
11:14To those of you who will be assigned to these units,
11:17Don't forget that you must fight very close to the enemy.
11:20And be sure to report the situation to our headquarters.
11:24who can send you B units equipped with long-range weapons.
11:51All of this represents about half of the white blood cells.
11:55The vast majority are our loyal allies, the polynuclear ones.
11:58These are the ones who fight directly and do not hesitate to absorb others.
12:22Our best friend, Lieutenant Little Fat.
12:25Yes. We are the combat infantry.
12:28So with us, there's no subtlety.
12:30Death to the invaders. And all means are justified.
12:39Of course, you shouldn't have a delicate stomach.
12:41But that's our life.
12:46Within the human body, we find not only invasions by hordes of enemies,
12:51but also dust, dirt, waste, and various toxins.
12:56These foreign elements to the human body must be treated appropriately.
12:59This is primarily the task of our phagocyte units.
13:03And that of our precious helpers, the macrophage units.
13:08With them, the place is clear.
13:11Dirt, various particles, viruses, bacteria, everything goes through it.
13:23Hey, look at that, these guys, you could say they wash whiter, huh?
13:26Especially since this whiteness is achieved without boiling.
13:51Yes, they swallow all our phagocyte blood cells.
13:54enemies dead or alive, sometimes even friends.
14:00Basophils fight allergies.
14:04Let's go!
14:09Among our aids, I would not want to forget the little interferon.
14:12It's an ultra-fast messenger.
14:13He runs to inform his neighbors when a cell is invaded.
14:17Where is he now?
14:19This gives them time to prepare their defense.
14:24Thank you for coming, Farmino.
14:27Invasion of the workstation, virus!
14:29All defenders are being called to their positions!
14:33Alright, everyone to your stations!
14:42Minor sector alert, nothing serious, so we're resuming.
14:45To fight effectively, we must know who is a friend and who is a stranger to the body.
14:49And if in doubt, remember that all cells in a human body are identified by a marker
14:54HLA identical.
14:56No other cell in the world can possess that document.
15:00Please present your identity cards.
15:03There, that's it, does that calm you down?
15:09And why don't I have an HLA card?
15:13Because you don't have a nucleus, and everyone knows that red blood cells are our
15:18friends, that they never attack anyone.
15:20And it wouldn't occur to any well-trained sentry in the corps to pick a fight with you, would it?
15:25Yes, but what about educated males?
15:27Don't worry, Grandpa! You're fit to defend yourself!
15:30But we are here to protect you, Hemot!
15:33Oh really? So?
15:36To defend red blood cells and other blood components, you must penetrate the blood vessels.
15:43Lieutenant Psy must have explained to you that it was feasible.
16:01Yes, our plasticity, that of our coating, is such that it allows us to slip in everywhere.
16:07So, don't hesitate.
16:10We're now running some tests. Tell me what you see on the screen.
16:14Virus, dangerous virus, coccystaphylococcus, enemy bacteria to be destroyed.
16:19And this? What do you see on the screen over there?
16:25A dangerous bacterium that needs to be eliminated?
16:28There you have it! If you paid attention in class instead of daydreaming, you'd stay after class, my young friend.
16:35As for the others, have fun and good luck with your work.
16:38Yeah !
16:41Look at it!
16:45Look at it!
17:00Look at it!
17:02Look at it!
17:12Subtitling by Radio-Canada
17:44Come on, cadets, a little discipline!
17:46Prepare to cross the wall
18:08Observe on the right, at approximately 3 PM, a suspicious cell
18:11What are you doing ?
18:38Abnormal cell, Lieutenant, malignant appearance
18:41During rapid growth, there is a risk of tumor development; it must be destroyed immediately.
18:43Well observed, immediate destruction
19:08Well done, young people
19:10Monitoring transforming cells is one of our important tasks
19:14It is thanks to our work that they do not invade normal cells.
19:24Here we are facing the jugular vein
19:26We're going to infiltrate it.
19:28Follow me
19:35We are heading towards the superior vena cava and the heart
19:38Our target, the right lung
19:44We're getting to the heart, right atrium, hold on tight
19:47It's going to be rocky
20:16Is everyone here?
20:18Okay, now let's move on to the lungs.
20:26Zone 37, this is where your first mission will begin, cadets.
20:30We will split up and each of you will patrol your own area
20:34Go ahead now, but stay in touch.
20:36I said, but please stay in touch.
20:43Let's go!
20:54Let's go!
20:57Let's go!
20:59I'm gone!
21:11Finally, my lungs need some fresh air.
21:13Here, patrolman T14 is on the inner surface of a bronchiole in the right lung.
21:17In contact with the outside world
21:19Everything is calm, Lieutenant
21:21Stay alert, you are in a high-risk area
21:24Large particles are released
21:25But beware of invaders
21:47Come on, come on
21:49There's nobody in sight
21:51So secure
21:56Come closer, don't be afraid
21:58It's okay, it's okay, no enemy in sight
22:01So let's get to work
22:02Target, mucosal cell
22:04We're going to have some serious bronchopneumonia.
22:07Ah, you're telling me that
22:08Ah, ah, ah
22:08Ah, ah, ah
22:13Ah, ah, ah
22:15Ah, ah, ah, ah
22:17Whoa, ah, ah
22:36And there you have it.
22:53Ah, ah, ah, ah, ah
23:11What is this? What do I see here?
23:14Too late, man.
23:15You're arriving much too late
23:17We are already thousands and thousands
23:21So you think it's going to happen like that, my dear father?
23:24T14 patrol boat here, yes
23:25Yes, alert, viral infection, transfer sector C
23:28Virus 346 identified
23:30Send reinforcements urgently
23:32Okay, number 14, competent white blood cell on its way
23:36In the meantime, a delaying action is being taken.
23:50So, it doesn't seem to be going well?
23:52Well, with the resources we have, there's not much we can do.
23:55Just wait a bit, you'll see.
24:00Ah, but you're B lymphocytes, that changes everything.
24:04Hats off to you, that's what I call efficiency!
24:05But there are still many others
24:10What did they teach you at school?
24:12You know very well that we can multiply.
24:21You have just participated in a routine action
24:24Number 14, compliments on your excellent judgment
24:27The infection has been contained.
24:32You see, the body's defense is based on vigilance
24:35Vigilance, information and coordination
24:41Now, other tasks await us.
24:45This is life
24:47The soul and the emptiness that flows serenely
24:52Let's take up the challenge
24:55To make it rhyme with joy
24:59The life
25:00The life
25:01The life
25:01The life
25:02The life
25:04The life
25:04The life
25:05That's life
