It's also, by the way, a characteristic of certain kinds of brain damage.

And down here the inferior vena cava.

The pattern is that those people, every one of them I looked at, who was a murderer, and was a serial killer, had damage to their orbital cortex, which is right above the eyes, the orbits, and also the interior part of the temporal lobe.

The eye socket is the bone receptacle in which the eye fits.

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.

I'll write that right here.

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

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

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.

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.

The back of the eye is a curved surface. The density of cones is highest tin the fovea. Which is where our eyes focus for reading or other activities.

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.

Smelling salts.

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.

And it sends off one vessel to the arm, one vessel up this way, the vessel over this way and then this arch gonna go down and splits like that.

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.

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

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

He's dying. Coronary blockage.

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.

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

Let's say this one goes towards my foot, and this is going to be now an even smaller artery.

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.

Survey the landscape below.

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

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

So let's start up on the left side.

It goes to the nucleus accumbens, all the way up to the prefrontal cortex, orbital frontal cortex, where decisions are made, high level.

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

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

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.

And as I say, most of them really die very horribly, 80 is very bad for you. now that means, that is really bizarre that one should ask the question why should we defy aging.

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

Here you have our tricuspid valve. And I'm gonna label it just as 'T'

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

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.

You can see two of the leaflets of the aortic valve working there.

Suddenly, I had an episode of catastrophic bleeding.

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

And that's why you see two things here, one here and you see one here and those are basically tubes.
