The left atrium and the left ventricle.

Returning to the house, the girls cross the atrium.

So what is that that is our left atrium.

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.

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

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

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.

So just like our right atrium we have one on the left.

At the same moment blood is going from the right atrium to the right ventricle, blood is actually also going from the left atrium to the left ventricle.

And the veins actually drain into a spot , directly into the right atrium.

Euclidean space, and spherical space.

Within five weeks, you start to see the early atrium and the early ventricles.

They're flying through their space, ocean space.

Go space, space. It is totally amazing.

You can see the atrium and the ventricles, how blood flows to our arteries and veins.

Here she is, drawing a picture of herself in the atrium of her father's enormous house.

That's to indicate deoxygenated blood and it goes back to the right atrium as deoxygenated blood.
