Two of the valves I'm gonna name, I'm giving them new names, something slightly different from what we've been referring to them by. These are the atrioventricular valves.

And then you can see the inside of the heart.

This attempt was made from cell 212.

Is it your cell?

Keep your eye on the valves and we'll talk about them as the blood moves through.

And the blood goes down into the right ventricle. And then, on the other side I'm going to label the last two chambers.

From the body... to the right auricle... to the right ventricle... and out the pulmonary arteries to the lungs.

So let's get started in the upper part of the heart. The Right atrium, It's right there.

You charge another inmate to clean his cell.

Blood flows from the right atrium to the right ventricle, then it goes to the lungs and from the left atrium to the left ventricle.

And it goes down into, you can probably guess how this one is called, is our left ventricle.

There's sort of illegal hustles, like you run a barbershop out of your cell.

So you've already learned that the valves got endocardium.

So I'm gonna just take some blue paint to indicate deoxygenated blood or blood without oxygen, I'm gonna paint in how it look.

You pay everything in stamps. Those are the currency.

Back in the late 19th century, the only source of heat in most homes was a big fireplace in the kitchen that was used for cooking and heating.

Let's start with blood going from the right atrium, this way into the right ventricle.

But now remember that blood is constantly moving through the heart, so in a previous cycle you actually had some blood that's coming back from the lungs and that's what's dumping into the left ventricle.

On the other side you have the mitral valve, which separates the left atrium from the left ventricle.

Just to orientate us this is the tricuspid (T) and this is our mitral (M).

Pookums?

Buildings are becoming bundles of services.

I've spent a lot of time in Finland at the design factory of Aalto University, where the they have a shared shop and shared fab lab, shared quiet spaces, electronics spaces, recreation places.

The wife!

Solitary.

That's my wife.

My wife...

My wife.

Which one?

Who lives here?

...that your wife is calling the morgues.

Exwife.

Meet my wife.

Yeah yeah yeah, got a hot wife... hot hottie.

It's mine!

It's mine.

Talk to your wife.

It's my wife.

The kitchen.

Let's start by labeling our heart, at the top, blood is coming into the right atrium, going to the right ventricle, it goes off to the lungs, comes back into the left atrium and then the left ventricle.

To the kitchen.

She begged for her life, Detective.

I think it's Jimmy's wife.

Too much AC?

You and the heat!
