And before I left the hospital, after a year of being hospitalized,

Move Word Left

Move Word Right

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 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.

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.

This vessel I'm gonna label let's say here, as the Aorta.

The reason is, they're treating other people like a computer, and the brain is too.

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.

Move the rifle around your head, not your head around the rifle.

Remove the ties that bind...

If you look at the first slide there, that's the temporal lobes, frontal lobes, parietal lobes, OK the lobes that constitute the brain.

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.

Just right at the back of my head.

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.

And these are called the bronchial arteries.

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

The olecranon, the medial epicondyle, the lateral epicondyle, the radial head, the location of the posterior interosseous nerve, and the biceps tendon in the antecubital fossa.

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

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.

Head injury on the right,

Wound's on the right side of his head.

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.

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.
