So that's called the visceral pericardium.

Now you can actually see the layers of the heart, the endocardium, myocardium and pericardium.

There are actually separate names for the two layers.

We have a layer called the pericardium.

In that gap you might have a little bit of fluid, but it's not actually cells. I guess that's the biggest point, it's not cells, it's just a little bit of fluid.

It goes around the ventricle and, as I showed you in the beginning, also around the atrium. It goes all the way up and covers both the left and right side.

This is our myocardium.

In metaphase I let me just copy and paste what I've already done the nuclear envelope is now gone.

Turbine release valve, activated.

Turn of that valve.

Open Valves 3 and 5.

I have it right here.

There are 3 layers to the heart muscle. I'm gonna go through all three layers, we'll start on the inside and work our way out.

When the red blood cells are entering the chambers of the heart, the part they're gonna see is the endocardium. This is what it looks like, this is that green layer all the way around that I've drawn now.

And to throw you a curveball, as I'm pretty sure you can handle it, this visceral pericardium, another name for it, because you might see it sometime, is the epicardium.

On the inside you have what's called the endocardium. I'm gonna draw the endocardium all the way around here, it goes all the way around the valves.

JH That's fantastic.

Water valve's sprung a leak.

Now look for the emergency valve release sequence.

The secondary flow valve should be behind you and to your right.

And now the nuclear membranes start forming around each of these two ends.

I finally got it. Meningitis?

This filling cap will go very snugly into an old bicycle tube.

I'm not doing a very good job making it look thin, but you can imagine what it is, what it could look like if I was to zoom in on it, basically something like that.

She died. From meningitis?

Hey, Ralph, wait a minute! Ralph!

Some time ago, I made an enemy.

We're about to cause the primary safety valves to fail.

Surface compression of valve sensors, Captain.

Կատարեմ պարզեցում

You said he was a research pathologist.

I shouldn't say cell wall.

Before we surrendered ourselves over to Juma, I opened the valves.

Water is our solvent.

We'll be outside. It's meningitis, isn't it?

That essentially cause the cell to either kill itself or its membrane to dissolve.

Take piping.

It's all coming back, isn't it?

So let's say that the solute is sugar.

So this muscle people don't talk about this muscle, or this is not the kind of muscle that you usually see people working on at the gym, but this muscle is called the diaphragm.

You have your overall cell.

Okay. Fascia's closed.

So how in the hell did it force itself closed?

I'm just trying to show you have more water molecules than sugar molecules.
