And let me actually show you where the blood vessels come from. These are called coronary vessels I just write the word coronary here.

Well, with the pig, at the baseline, before we blocked the pig's artery to simulate a heart attack, that was the signal.

There is actually a little spot right there that they drain in to.

And then, when the heart is ready to pump it back out, it goes into this artery, and the name of it is the aorta.

And so I think we can roll the video that we have.

This is now going to dump into what we call a venule.

You might think, Boy, is there a context expensive grammar out there? What's the opposite of free?

I'm going to do some surgery here.

Hey, there's no pulse.

I was afraid something had happened to you.

I'll write that right here.

The Balkan Mountain range runs across Bulgaria from west to east.

I could just write artery and vein and essentially they would be behaving this way.

Now, to start the journey, it's gonna have to out of the left ventricle and into the largest artery of the body.

Coronary vessels So, coronary artery and vein.

One is a positive gate... the other a negative gate.

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

And on the right you actually see a carotid artery that was engineered.

I think she cut both arteries. I could hardly feel her pulse.

And you might say, well that wasn't so difficult. I'll say bronchial vessels, because there are also some veins coming off.

So these two veins, the superior vena cava and the inferior vena cava, are dragging the blood back to the heart, and, generally speaking, these are all considered, of course, veins.

Alright, so the mean for one group won't be the exactly the same as the mean for the next group.

Right it's gonna have to go away from the heart. So that's the aorta. The aorta actually has the little arch like that.

My pulse is slow.

So you have these arteries right over here, the red tubes. Those are arteries. and then the blue ones are veins.

The veins of leaves.

Two. I knew that. Two households...

There's also another one over here called the superior vena cava, and this is bringing back blood from the arms and head.

And at the bottom here, you can't see it because it's on the other side of the heart, but there's another vein called the inferior vena cava.

Well, these vessels, all of them, together are called coronary vessels.

An African economy can be broken up into three sectors.

And actually it stop there because of my arrows, but you can actually see now deoxygenated blood kind of goes from the right ventricle, through the pulmonary trunk, through the arteries and into the left and right lung.

You have a regular pulse.

My pulse is fast.

I saw a chain of mountains.

That's good Herby, that's lovely no change.

But when they go away, so does much of the drinking water.

So this is more challenging

You know, I think maybe you will. One forty five over 70 with a pulse, 80.

Respiration fair, pulse fair.

Smelling salts.

Where are the Chocolate Mountains?

O rowan mine

To the Gate, to the Gate!

Inferior vena cava, and this is the large vein that brings back all the blood from the bottom half of the body.
