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.

Automated real time traffic information exchange.

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

And it's job is of course to make sure the blood does not go from the left ventricle back to the left atrium by accident. Wants to make sure there is forward flows.

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.

And of course, through all of these lines are flowing unstructured language.

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.

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

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.

Well after that it's gonna go this way it's going to go to this vessel and it's gonna split.

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.

Well, whose turn is it?

Transportation simulator

A startup, okay.

Smelling salts.

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

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

I'm going to do some surgery here.

We were stuck up in heavy traffic this morning.

So she ran away from home. And then went astray.

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.

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 was upset by the news of the traffic accident.

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

Your pulse is normal.
