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

He's dying. Coronary blockage.

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

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

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

Coronary vessels So, coronary artery and vein.

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

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.

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

Stay clear of the hepatic artery.

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

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

I mean, you've got red ones, and blue ones, and the blue ones are the veins, and the red ones are the arteries but are they part of the systemic flow, or pulmonary flow, or something else?

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

This is an arterial, right.

And you can see, it's lumpy bumpy.

What's happening between these two, time like here, is that blood is actually squeezing out because the pulmonic and aortic valves just opened, blood is squeezing out and going to the whole body.

And I've drawn it as one tube with no split and this is the pulmonary trunk. Pulmonary trunk.

So you've got a couple of arteries that are branching off and these are also part of the systemic circulation systemic circulation.

In concluding the knee exam, it's important to document a neurovascular exam.

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

In concluding the ankle and foot exam, it's important to document neurovascular.

It was terribly dangerous. (Laughter)

We can understand functionality. This is really important.

Just a moment, Jethro. Is the needle in his femoral artery, Mr. Palmer?

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

In concluding the hip exam it is important to document neurovascular exam.

This is an artery. And blood is actually going through the artery, that way.

He had a neck wound that severed his carotid artery, and that made him bleed to death.

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

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

What nitric oxide does is it dilates blood vessels, so it lowers your blood pressure.

So blood is headed towards the lungs, going first through the trunk, and of course after the trunk, there is left and right I write that up here pulmonary arteries are next.

So let's get a little more precise with the words we've been talking about, especially with heart disease and heart failure and all of the rest.

This is what we call a plaque.

And these are called the bronchial arteries.

And this is of course the aorta. This is my aorta.

His vitals are spiking.

So, those cells are going to need blood vessels supplying them as well. So, that's what the coronary blood vessels are.

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.

Resisted digit abduction tests the ulnar nerve.

BBL's a liter in the field and only one PIV.

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

While the heart is not moving the surgeon can reroute blood vessels, the part of the heart muscles where clogged arteries are restricting the flow.
