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

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

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

His vitals are spiking.

Brachial artery pumps 30 liters of blood a minute.

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.

Up into the ascending aorta.

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

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.

It doesn't have any veins.

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.

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.

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.

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.

MAP's at 55.

In the jugular preferably. okay.

In your jugular on the side of your neck.

Midway up her right thigh?

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.

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

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

The patient moved his lips slightly.

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.

So let's start up on the left side.

The risk of permanent damage Seizures, aneurysms, memory loss, death...

Start the drip. Okay. I can't find a vein.

The aneurysm has been repaired.

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

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

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

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'
