And then the left ventricle.

We're gonna start our journey here at the right ventricle.

Now we're in the left ventricle.

Now in the left ventricle, after it's done pumping, it expands and that oxygenated blood flows into the left ventricle.

So this is his right ventricle.

So this is the right ventricle, down here.

left ventricle and then the left ventricle pumps that oxygenated blood to the rest of the body via the non pulmonary arteries.

So just like before where we went from the right atrium to the right vertricle, now we're going from the left atrium to the left ventricle.

You're saying, hey, why is it the right ventricle?

Then it shows up in the right ventricle, right?

It actually passively flows into the right ventricle.

The left ventricle is involved in 50 67 of individuals.

And the blood goes down into the right ventricle.

And then it goes into the right ventricle. This is chamber number two.

From the right atrium, it gets pumped into the right ventricle.

But what we have is, the heart pumps de oxygenated blood from the right ventricle.

So blood goes into the rigt verticle and where it goes next.

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.

And it's job is of course to make sure the blood does not go from the left ventricle back to the left atrium by accident.

In the middle, you can see that little structure squeezing out, that's the left ventricle, pushing blood out through the aortic valve.

The mitral valve opens when the pressure in the left atrium is greater than the pressure in the left ventricle.

And the Arotic valve is going to be what divides the left ventricle from this giant vessel that we talked about earlier.

Then the left ventricle the ventricles are what do all the pumping it squeezes and then it pumps the blood into the aorta.

The obex (from the Latin for barrier ) is the point in the human brain at which the fourth ventricle narrows to become the central canal of the spinal cord.

And for the moment I'm gonna kind of pause the journey here. So we've gone from the right ventricle around to the lungs, back again into the left atrium.

Well, blood leaves the right ventricle, goes through a valve and after, on the other side you've got, this area right here.

The ventricles do all the pumping, then the ventricle contracts and pumps this blood right here and you don't see it, but it's going behind this part right here.

And it passively, once the right ventricle pumps and then releases, it has a vacuum and it pulls more blood from the right atrium.

On the third floor, sir. On the third floor.
