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

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.

And then it goes into the right ventricle.

The heart is located in the chest.

And once the blood is in right atrium, it's going to head down into the right ventricle.

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.

I'll go through the chest, go straight into the heart.

Once you've made it, the installation is quite easy.

I would look at the tongue.

We're gonna start our journey here at the right ventricle. So what's the first thing that kind of comes across?

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

No reason. Patient is in asystole. Continuing chest compressions.

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.

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.

So you're probably feeling pretty comfortable with the diagram of the heart, but let me just go ahead and label a few things, just to make sure we're all on the same page.

We're gonna actually follow the path of blood after it leaves the right 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.

It's abnormal to have the heart on the right side.

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.

Many shots with their weapons and shot the bodies. lt b gt shots at the center of mass . lt b gt

And they show central surface brightness versus radius in the top left.

He felt patriotism rise in his breast.

In the new cycle you have a bit of blood that's going from the right atrium to the right ventricle.

When it crumbles (when it crumbles)

Right, right, right!

So blood would flow from the left ventricle, into a place it shouldn't be going, the right ventricle.

So what is that that is our left atrium.

She felt her heart turn over in her chest.

Or the inventor of the next internet

So these are the two direction the blood is going to be flowing.

My breasts.

'I've a right to think,' said Alice sharply, for she was beginning to feel a

Follow the ball until the end.

Right there, right there.

The fire of ambition burned within her.

And I know you can only see two in my drawing and that's just because my drawing is not perfect. And it's hard to show kind of flap coming out of juby you can imagine it.

Makes my heart hot

Cold brain

Ehoheh oh oh oh ohehoh

You know, and... I wish I could just talk to her.

Man, people are cruel.

Isn't this exciting?

Down into the heart?
