And then you can see the inside of the heart.

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.

If we had a high conducting or... what do you call them?

Is it here, only here, and what?

The first into the right atrium. This is chamber number one.

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.

So the blood from the arterial side is coming from the aorta and on the venous side it's actually not even dumping into the inferior or superior vena cava, kind of little known fact that is coming directly into the right atrium.

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

Ee Shim Jun Shim! (tactic understanding)

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

So unlike the CAT scans, X rays, thalliums, for women whose breast is in the way of looking at the heart, every time we order something that has even a small amount of radiation, we say, Do we really need that test?

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.

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

Pookums here really has her heart set on another R2.

Mi Na first!

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.

The pulmonary veins drain blood and into the left atrium, right.

So what is that that is our left atrium.

Well, no...I mean, we've known each other a long time.

This is chamber number two. It goes to the lungs and then back up to the left atrium.

Doing backup training on my days off.

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

I had to apprentice myself in order to become a pottery master.

Even if I merely end up hurting myself

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

Pookums?

like the one that you can see here in the photo.

We gotta tie the GPS to the mainframe.

That is potentially hyperconductive.

John Connor. Prophesized leader of the Resistance.

Buildings are becoming bundles of services.

For example, I can make a large circular rail here.

So we've gone from the right ventricle around to the lungs, back again into the left atrium.

And then it's gonna come out on the other side, in the pulmonary veins.

This is the second chamber of the heart. And it gets there by passing through the valve.

The wife!

Solitary.

That's my wife.

My wife...

We're working on our college essays. Send them in.

It's a superconducting chip. No cooling needed.

So the first branches go and serve the heart. So it's kind of the first to get systemic circulation blood.

Grisha, someone's knocking on the door.
