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

Or from the point of view of the person whose heart it is, it's on the left.

He's dying. Coronary blockage.

They're taking the de oxygenated blood away from the tissue of the heart.

Officially, they're characterizing that it was a coronary brought on by systemic shock.

Coronary vessels So, coronary artery and vein.

This right over here is called the left coronary artery or LCA.

So ischemia is deprivation of blood flow and oxygen downstream from this right over there.

Now, that inability to properly pump not just the cell, but the whole heart that is heart failure.

And you can see, it's lumpy bumpy.

And so when people talk about arteries getting blocked or getting clogged, they're talking about the coronary arteries.

And remember I call them arteries, because they're going away from the heart. And there are two arteries, so pulmonary arteries left and right pulmonary arteries.

That's what we call coronary artery disease, or heart disease.

That's not very nice, but, after all, we had to find out what the answer is.

Well, what is needed for the earliest possible warning of a heart attack?

On the other side you have the mitral valve, which separates the left atrium from the left ventricle.

His vitals are spiking.

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.

The syndrome, the female pattern now is called microvascular coronary dysfunction, or obstruction.

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

It doesn't have any veins.

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

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.

Remove the ties that bind...

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.

Now suppose you live in a certain part of a certain remote place and you have a loved one who has blockages in two coronary arteries and your family doctor refers that loved one to a cardiologist who's batting 200 on angioplasties.

Smelling salts.

If the artery gets nicked, how long do i have?

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.

I'm going to do some surgery here.

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

Remember the heart itself is a muscle. It itself needs oxygen.

And I hesitated there just to make sure I got that because it's taking blood away from the heart.

No lesions. No aneurysms.

MAP's at 55.

In the jugular preferably. okay.

In your jugular on the side of your neck.

Midway up her right thigh?

And, from the aorta, I'm actually not drawing all the branches of the aorta, but from the aorta, it's going to go down into my belly, and it's going to branch towards my left leg and my right leg.

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

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.

Then these vessels and all that they trying to get will be called, these vessels, this will be my, make sure I get my right and left straight, this is my left pulmonary artery.

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