HAP- Intro to Immune System

Audio Transcript Auto-generated

• 00:01 - 00:01

  Hi guys.

• 00:02 - 00:02

  Date you.

• 00:03 - 00:07

  Um, hopefully we didn't have any issues accessing anything again.

• 00:08 - 00:09

  If you did, please make sure that your email me

• 00:10 - 00:10

  It's my way.

• 00:10 - 00:10

  I know.

• 00:11 - 00:13

  And I can make sure that we fix whatever problem

• 00:13 - 00:13

  we have.

• 00:14 - 00:17

  Uh, so we're gonna talk a little bit about the

• 00:17 - 00:18

  immune system today.

• 00:19 - 00:19

  The limp systems.

• 00:20 - 00:20

  Pretty straightforward.

• 00:21 - 00:24

  Okay, Basically, is there to feed aid to the immune

• 00:24 - 00:26

  system? So the more we're gonna talk about the immune

• 00:27 - 00:29

  system, the more you're going to see how the lift

• 00:29 - 00:30

  system is.

• 00:30 - 00:33

  They're going to help our Indian system reacts or whatever

• 00:34 - 00:35

  possible passage and gets in our body.

• 00:37 - 00:39

  So the first thing I talk about is immunity.

• 00:40 - 00:41

  Okay. What does it mean?

• 00:41 - 00:44

  To have immunity or to be immune from something?

• 00:45 - 00:49

  Okay. So immunity is the ability to resist damage from

• 00:49 - 00:51

  a foreign substance, whether that substance be a microbe and

• 00:52 - 00:54

  talks in, uh, even your own cancer cells.

• 00:55 - 00:57

  Remember, cancer cells are your own cells that mutate.

• 00:58 - 00:58

  Ah, a virus.

• 00:59 - 01:00

  Bacteria. Whatever.

• 01:01 - 01:04

  Okay, so that stuff gets in our body and it

• 01:04 - 01:05

  can do damage to the cells in our body, so

• 01:06 - 01:07

  we need to figure out a way to make sure

• 01:07 - 01:09

  that we can resist whatever damage happens.

• 01:11 - 01:12

  So we have two different types of immunity.

• 01:12 - 01:13

  We have innate an adaptive.

• 01:14 - 01:16

  Okay, the first war and talk about is innate.

• 01:17 - 01:19

  And just like the name of itself, it's something that

• 01:20 - 01:22

  everyone haps as soon as you were born.

• 01:22 - 01:25

  You have all of these immunities working for you 24

• 01:26 - 01:28

  hours, seven days a week for your entire life.

• 01:29 - 01:31

  Okay. Of defense against any pathogen.

• 01:32 - 01:35

  Ok, so anything that it can possibly get into our

• 01:35 - 01:36

  body and they got us tickets.

• 01:37 - 01:38

  This is what a defense against.

• 01:39 - 01:42

  But it accomplishes this by several six physical barriers.

• 01:43 - 01:46

  Chemical mediators sells an inflammatory response.

• 01:47 - 01:51

  Okay, so we're gonna talk about those little bit more

• 01:51 - 01:51

  in depth.

• 01:51 - 01:52

  So physical barriers.

• 01:53 - 01:54

  This is your first line of defense.

• 01:55 - 01:57

  Okay, This is your skin and mucous membranes.

• 01:59 - 02:01

  Without skin, things would easily get into our body.

• 02:01 - 02:03

  Skin is very, very, very, very important.

• 02:04 - 02:07

  Okay, if you think back to way, way, way back

• 02:07 - 02:08

  to unit two.

• 02:08 - 02:09

  We talked about the skin.

• 02:09 - 02:11

  We actually talked about how your skin is also slightly

• 02:12 - 02:16

  acidic. That acid keeps bacteria, fungi, viruses from actually growing

• 02:17 - 02:21

  on your lovely skin and he being things out.

• 02:22 - 02:24

  One of the ways that we can get around skin

• 02:24 - 02:26

  is when we have a cut, okay?

• 02:26 - 02:31

  Or buy a new, obviously ingesting something either through the

• 02:31 - 02:34

  oral cavity or the nasal cavity, or even gets through

• 02:34 - 02:34

  through your eye.

• 02:35 - 02:37

  Okay, all of those airways for things to get into

• 02:38 - 02:38

  our body.

• 02:39 - 02:42

  Now, these openings that I'm talking about, we do have

• 02:43 - 02:44

  defenses in them as well.

• 02:45 - 02:50

  Tears, saliva and urine all washed away pathogens that could

• 02:50 - 02:52

  possibly get into our body.

• 02:53 - 02:55

  So that is why you have your eyes are moist

• 02:55 - 02:55

  all the time.

• 02:56 - 02:59

  Your tears are constantly being produced to make sure that's

• 02:59 - 02:59

  another barrier.

• 03:00 - 03:03

  Okay, obviously, mucus in your nasal cavity, Um and then

• 03:03 - 03:06

  saliva actually has specialized chemicals in it.

• 03:06 - 03:09

  That we'll talk about a limit later and to make

• 03:09 - 03:12

  sure that things don't get in when we're eating food

• 03:13 - 03:14

  or so on and so forth.

• 03:17 - 03:18

  So, coco mediators.

• 03:19 - 03:22

  Hey, these are chemicals that are body naturally produces, and

• 03:22 - 03:25

  these can kill my groves and prevent entry into cells.

• 03:26 - 03:29

  So remember in the video when beware Washington flew video,

• 03:30 - 03:33

  they showed how the viruses can't replicate, but what they

• 03:33 - 03:36

  do is they invade ourselves in order to replicate day.

• 03:37 - 03:39

  Same thing with bacteria bacteria can replicate on its own.

• 03:39 - 03:43

  But it utilizes our cells to actually speed up the

• 03:43 - 03:44

  replication process of bacteria.

• 03:46 - 03:48

  So these chemicals that we have are very important.

• 03:49 - 03:51

  The first number and talk about isn't nice, those dime

• 03:52 - 03:52

  okay, life.

• 03:53 - 03:55

  So this time I don't write me for lice, All

• 03:55 - 03:58

  right, there's another thing that we need in order to

• 03:58 - 04:02

  make sure that we counteracted things going on around us.

• 04:02 - 04:05

  We find this hand tears since saliva, and they are

• 04:06 - 04:07

  there to make sure that we kill any bacteria.

• 04:08 - 04:10

  Now it's not foolproof.

• 04:10 - 04:14

  These things aren't 100% but these things are constantly working

• 04:14 - 04:14

  for you.

• 04:15 - 04:17

  So if you think about it all right, any food

• 04:18 - 04:20

  that you take that something external that you're not putting

• 04:21 - 04:25

  internally, so bacteria lose on almost any service.

• 04:26 - 04:29

  So that's why it's really important to make sure that

• 04:29 - 04:31

  when you are eating food that you cook it to

• 04:31 - 04:34

  temperature, especially in this day and age right now, with

• 04:34 - 04:37

  the Corona vice crying on food that where you have

• 04:37 - 04:38

  to touch the surface and touch the food and then

• 04:39 - 04:41

  put it in your mouth that's gonna transfer bacteria or

• 04:41 - 04:42

  viruses as well.

• 04:43 - 04:45

  So we want to make sure that we're living that

• 04:46 - 04:49

  possibility of getting into our body by having that life's

• 04:49 - 04:52

  design, our saliva, the mucus, some braids you're like That's

• 04:53 - 04:53

  a physical bearer.

• 04:53 - 04:54

  Why's that?

• 04:54 - 04:54

  Undercover commuters?

• 04:55 - 04:58

  Because the mucus itself in the mucus when we trapped

• 04:59 - 05:03

  something, it can actually have chemicals harming fist that will

• 05:03 - 05:07

  break down and kill the bacteria or the viruses, Um,

• 05:07 - 05:09

  or in my growth, that against into our nasal cavity

• 05:11 - 05:13

  histamine e, we had talked about his team before.

• 05:14 - 05:14

  Remember his swing?

• 05:15 - 05:17

  Is that being that you loved to hate if you

• 05:17 - 05:22

  have allergies, Okay, Histamine actually has a very specific, uh,

• 05:23 - 05:27

  role in this immune system, and it promotes inflammation.

• 05:28 - 05:29

  My causing vaso die elation.

• 05:30 - 05:32

  Now, remember, Bassett violation is the vessels getting bigger?

• 05:33 - 05:35

  Okay, so by the vessel is getting bigger.

• 05:36 - 05:38

  We're increasing blood flow to that area.

• 05:38 - 05:41

  When we increased blood flow to that area, you're also

• 05:41 - 05:43

  increasing the amount of white blood cells that are getting

• 05:44 - 05:44

  to that area.

• 05:46 - 05:48

  It is also why, when you have allergies in your

• 05:48 - 05:52

  body completely overreacts to like Poland in your body.

• 05:53 - 05:55

  Um, that you have a runny nose.

• 05:56 - 05:59

  You have watery eyes because without vassal dilation, we also

• 05:59 - 06:03

  amp up the saliva and tear process to make sure

• 06:03 - 06:05

  other things don't get into our body.

• 06:06 - 06:08

  Now, the last Morgan talk about what she goes should

• 06:08 - 06:12

  remember from again the video we watched in cross is

• 06:12 - 06:12

  the interference.

• 06:14 - 06:17

  Okay, The proteins have protect against viral infections by stimulating

• 06:18 - 06:20

  surrounding cells to produce antiviral proteins.

• 06:21 - 06:24

  So remember, the video is actually interfere on one and

• 06:25 - 06:25

  interfere on two.

• 06:26 - 06:29

  Yeah, So there are different stages for this interfere on

• 06:29 - 06:31

  and we're going to get more in depth when we

• 06:31 - 06:34

  talk about the adaptive immune response.

• 06:35 - 06:38

  How those interference are released at what stage is they're

• 06:38 - 06:41

  released in order for our bodies to be able to

• 06:41 - 06:44

  compact something foreign inside of us.

• 06:46 - 06:47

  The inflammatory response.

• 06:47 - 06:49

  This kind of goes hand in hand with histamines.

• 06:50 - 06:54

  Okay, so it involves those chemical mediators on and other

• 06:54 - 06:56

  cells and it's due to an injury.

• 06:57 - 06:59

  So any time we have an injury, your body is

• 07:00 - 07:02

  kind of like, OK, we have to fix it.

• 07:02 - 07:04

  But we also have to make sure something didn't get

• 07:04 - 07:06

  in. Okay, That's why if you've ever cut yourself, even

• 07:06 - 07:08

  though it's a small cut, you also feel like there's

• 07:08 - 07:10

  a little swelling around the cut.

• 07:10 - 07:13

  And that's because this inflammatory response is occurring.

• 07:13 - 07:16

  What's happening is we're want more blood to rush in

• 07:17 - 07:20

  that area to bring more white blood cells to make

• 07:20 - 07:23

  sure something didn't get past our skin.

• 07:24 - 07:28

  And in the cut and into our body, we basically

• 07:28 - 07:33

  joined Inflammatory splits causes more chemical mediators to occur again

• 07:33 - 07:34

  and again and again.

• 07:34 - 07:36

  This is kind of like a domino theory, or it's

• 07:36 - 07:37

  like you triggered one.

• 07:37 - 07:38

  The rest is going to fall.

• 07:42 - 07:45

  Okay, so in age is kind of pretty straightforward.

• 07:46 - 07:47

  It's what you have.

• 07:48 - 07:51

  It's You're always gonna have it, no matter what you're

• 07:51 - 07:53

  born with it it's there to protect you.

• 07:53 - 07:54

  Yeah, Okay.

• 07:54 - 07:57

  In ages, not 100% foolproof, though.

• 07:58 - 08:00

  That is why we have the second part of our

• 08:00 - 08:02

  immune system called the adaptive immune system.

• 08:04 - 08:06

  Um, and this is what we call a defense that

• 08:06 - 08:10

  involves specific recognition of a specific answer, Jim.

• 08:10 - 08:13

  Okay, so now you're gonna be like Auntie Gin.

• 08:13 - 08:15

  One of those words were gonna discuss a little bit

• 08:16 - 08:18

  more about when Auntie gin is before I know.

• 08:18 - 08:21

  Think of an answer soon as something back you don't

• 08:21 - 08:23

  want in our body our bodies like Wait a minute.

• 08:23 - 08:24

  That's not good.

• 08:25 - 08:25

  I'm gonna kill you.

• 08:26 - 08:28

  So this is something that we get after birth.

• 08:29 - 08:32

  So as we're growing up and throughout your entire lifetime,

• 08:32 - 08:37

  we're developing this adaptive immune system again, as I said

• 08:37 - 08:38

  are in a systems great.

• 08:38 - 08:40

  It's working all the time for us.

• 08:40 - 08:40

  But it's not 100.

• 08:41 - 08:41

  Some fool proof.

• 08:42 - 08:45

  So adaptive is what's triggered when the in date system

• 08:45 - 08:46

  is no longer working.

• 08:47 - 08:50

  Our dentist is slower than our innate system because we

• 08:51 - 08:55

  have to look for those specific cells that will fight

• 08:55 - 08:56

  against its specific androgen.

• 08:57 - 08:59

  And we have trillions of cells in our body, so

• 08:59 - 09:01

  it takes a while to find the right one.

• 09:02 - 09:04

  However, are adaptive means system has memory.

• 09:05 - 09:07

  Okay, It's like an elephant it will never forget.

• 09:08 - 09:12

  Okay, so if we find a specific auntie gin one

• 09:12 - 09:14

  time and where body figures it out and we trigger

• 09:15 - 09:18

  those cells to fight back, if we ever get that

• 09:18 - 09:21

  auntie gin exposure again, our body will remember and will

• 09:22 - 09:24

  respond a lot quicker this second time because of that

• 09:25 - 09:29

  memory, we use lymphocytes, those B and T cells.

• 09:30 - 09:33

  Okay. And we have two types of this inductive mean

• 09:33 - 09:37

  system. We have an antibody mediated and sell me.

• 09:37 - 09:39

  And again, we'll get more and death that a little

• 09:40 - 09:40

  later on.

• 09:42 - 09:44

  So these terms that we need to talk about an

• 09:45 - 09:48

  auntie gin and Auntie gin is a stub since substance

• 09:49 - 09:55

  that stimulated and immune response cases giving bacteria, viruses, pollens,

• 09:56 - 09:56

  food, drugs.

• 09:57 - 10:01

  Okay, whatever it is, it makes our immune system set

• 10:01 - 10:01

  up ago.

• 10:01 - 10:02

  Hey, something's wrong.

• 10:03 - 10:04

  We need to do something.

• 10:05 - 10:06

  Okay? No.

• 10:06 - 10:09

  Sometimes these engines are not harmful, like allergies.

• 10:10 - 10:13

  When you have allergies, pollen is not going to kill

• 10:13 - 10:15

  you. But your immune system looks at it and goes

• 10:15 - 10:18

  on. My God, it's the plague, and it overreacts.

• 10:19 - 10:22

  And hence when we have lovely allergies now, a self

• 10:22 - 10:25

  auntie gin is a molecule that's produced by our own

• 10:26 - 10:28

  body, and our body looks at it and it goes,

• 10:29 - 10:30

  You're not supposed to be here, even though our own

• 10:31 - 10:31

  body produced it.

• 10:33 - 10:35

  Army, a system like setting goes, You're not supposed to

• 10:35 - 10:37

  be here and starts attacking our own cells.

• 10:38 - 10:40

  These air called auto immune diseases.

• 10:41 - 10:44

  Where auto meaning that it's yourself immune system.

• 10:44 - 10:47

  Meeting that yourself immune system is attacking your own systems

• 10:48 - 10:50

  inside your body, huh?

• 10:51 - 10:54

  A lot of these you could talk about when we're

• 10:54 - 10:54

  going to talk about.

• 10:55 - 10:56

  But, Luke, this is a big one.

• 10:56 - 11:01

  H ideas One, uh, multiple sclerosis does we talked about

• 11:01 - 11:02

  before his line.

• 11:02 - 11:05

  So there's a lot of them out there, and it's

• 11:05 - 11:08

  unfortunate, but we're not 100% sure how to stop your

• 11:08 - 11:12

  own body from kind of killing itself.

• 11:13 - 11:17

  Unfortunately, at this time, they can put you on medication

• 11:18 - 11:20

  that suppresses in your immune system, but that opens you

• 11:20 - 11:23

  up toe having a whole lot of other issues or

• 11:23 - 11:28

  getting, uh, well, lucky for their sicknesses or viruses.

• 11:29 - 11:30

  Bacteria so on and so forth.

• 11:31 - 11:33

  And not having an immune system being able to fight

• 11:33 - 11:35

  back. Now.

• 11:35 - 11:37

  Antibodies okay.

• 11:37 - 11:40

  And bodies is the protein our body produces in response

• 11:41 - 11:41

  to an auntie gin.

• 11:41 - 11:45

  So your antibodies are basically there to go attacks the

• 11:45 - 11:47

  Auntie Gin and make sure that the insurgent can't spread

• 11:48 - 11:49

  anymore in our body.

• 11:51 - 11:53

  All right, so you got three questions to answer today.

• 11:54 - 11:55

  Okay. What is an answer?

• 11:55 - 11:58

  Jin How do antigens alter our bodies to pop our

• 11:59 - 11:59

  Ultra woo?

• 12:00 - 12:00

  That's us.

• 12:00 - 12:00

  Must be elder.

• 12:01 - 12:01

  So be alert.

• 12:03 - 12:07

  Alert our bodies to possible danger if our body attacks

• 12:07 - 12:07

  our own antigens.

• 12:08 - 12:09

  What is that called?

• 12:10 - 12:12

  And then do our bodies boys attacked the right Auntie

• 12:13 - 12:14

  gin. What is it causing me?

• 12:14 - 12:16

  A system overreacts to an Auntie gin.

• 12:17 - 12:19

  Okay, so if you've been listening, as you shall should

• 12:19 - 12:21

  be, you should be able to answer those three questions.

• 12:22 - 12:22

  No problem.

• 12:23 - 12:25

  Now, kind of a layout for what's going on for

• 12:25 - 12:26

  the rest.

• 12:26 - 12:29

  The week tomorrow, we're going to talk about the cells

• 12:30 - 12:31

  of the immune system.

• 12:32 - 12:34

  You guys should also go listen to the voice over

• 12:34 - 12:37

  that I have of the flow chart of the immune

• 12:37 - 12:38

  system that we have.

• 12:38 - 12:40

  Um, sugi uploaded soon.

• 12:42 - 12:43

  It is pretty sure Ford.

• 12:44 - 12:46

  It's just looking at the two different ranges.

• 12:46 - 12:49

  We have an A in adaptive going from there.

• 12:50 - 12:52

  After that, we're gonna talk more and dive more into

• 12:53 - 12:54

  adaptive immune system.

• 12:54 - 12:56

  And again, there'll be another flow chart for that.

• 12:56 - 12:57
