I have an irregular pulse.

Parentral on the other hand, is shown over here.

Let's type and cross her for six.

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

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?

So in 1980, some researchers did a study on a drug called lorcainide, and this was an anti arrhythmic drug, a drug that suppresses abnormal heart rhythms, and the idea was, after people have had a heart attack, they're quite likely to have abnormal heart rhythms, so if we give them a drug that suppresses abnormal heart rhythms, this will increase the chances of them surviving.

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.

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.

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.

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.

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

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

But, actually lungs are kind of interesting in the sense that there is a lot of mixing going on.
