Hi, I'm Ed Hope, a junior doctor in the UK

where I explained medical things in simple terms like

the other week I looked at the medical anime Cells at Work

but your response to the video did as well

guys thank you so, so much for all the support

So it's only fair that I check out episode number two

So, we're following our red blood cell again

as she carries the oxygen around the body

and she's lost, like she spent most of the first episode

but we get properly introduced to the very cute platelets

The medical term for them is the thrombocytes

"THROMBO" because they're involved in creating a thrombus-

- and CYTE is a name we give to any mature cell

and this ties in because platelets are actually very tiny

about a third of the size of a red blood cells

That's because their job is to really plug the small gaps

And this episode is called a scrape wound

so we're probably going to find out all about how they work and everything they're carrying as well

Aw, I like that the platelet calls the red blood cell "Big Sister"

because the two are related in the kind of family tree

So they share the same ancestry of cells all produced

in the center of the bones, what we call the bone marrow

Quite literally means "production of blood"

You've probably heard of these in lots of medical research because they've got the

ability to turn into lots of different cell types.

One of these cell types is the myeloid progenitor cells

And in turn, they can develop into lots of different cells as well

so one our of fan favorites in Cells at Work.

ERYTHRO means red and CYTE, as we said earlier,

The myeloid progenitor cell can also turn into a megakaryocyte

which sounds like something out power rangers, doesn't it?

And this is the cell that produces platelets

So when the red blood cell and the platelets refer to themselves

as sisters, you know, they pretty much are

And also just to complete the picture, this myeloid progenitor cell

I mean the whole city, representing the skin,

has been damaged, but this kinda fits right? Anyone that's

had a scrape wound or an abrasion before will know that

you'll notice some discoloration for awhile, sometimes

you'll be permanently left with some kind of scar, so

maybe I underestimated - obviously these guys are very small

so even small injuries are gonna have big effects

There he is, the man! I'm not sure white blood cells quite

do this with red blood cells, but you know

Okay so in the first episode we had to deal with

one bacterium, the streptococcus pneumoniae

a whole bunch, 'cause one of the functions

of the skin is to be a physical barrier between the outside

world and your bodies, so if that gets broken, then any

happily living on our skin, that doesn't effect us, can then get under

And the classic example of a bacterium that normally lives on our skin

and doesn't cause any problems is staphlyococcus aureus

so the staphlyococcus, remember I talked about in the last video

We can see that the shape they've made the bacterium

that's obviously why they've picked this color

because staphlyococcus aureus has this kind of pigment

A gold yellow-y pigment that's part of its

harder for the immune system to break down the bacteria
