This is now going to dump into what we call a venule.

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

I'll write that right here.

Into the IV, yes.

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

So you have these arteries right over here, the red tubes. Those are arteries. and then the blue ones are veins.

It's just like a chest cold.

A continuous I.V. drip and governmentissue antipsychotics,

Slashed carotids and windpipes so no one would hear.

There's also another one over here called the superior vena cava, and this is bringing back blood from the arms and head.

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.

Start a largebore IV. Keep it open.

So this is more challenging

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

Chickenpox at age 8. Bronchitis at 14.

And it generally travels through two major kind of vessels.

I'm going to do some surgery here.

And this outer layer, this is the vasculature, which is incredible, around a human brain.

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

You cover up the vein, you do the same thing, you have one tiny opening here, and this opening, let's have it go down so it looks the same, and this opening is to a bicycle pump.

A venule, and this venule is gonna basically then feed into many, many other venules.

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

When she catches a cold, she often develops bronchitis.

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

They would ordinarily support fish and other wildlife.

And fortunately he didn't die.

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?

So you think of alternative mechanical parts.

She was being given medicine intravenously.

So Superior Vena Cava and Inferior Vena Cava.

Maybe from the second toe, and it's gonna basically all kind of gather together, and again, to a giant, giant set of veins.

I need two largebore Ivs, 6 units Oneg, type and cross for 6 more units,

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

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.

Is she doing well?

A little vein in his head popped, and that was that.

I hope my veins don't pop.

So, here you have a giant vein, this is a vein, and you have an artery.

I had hoped to die of a lung disease or at least a chronic bronchial emphysema.

You know, maybe veins are dumping in here now, maybe another vein dumping in here, and these veins are all going to dump into an enormous vein that we call the inferior vena cava.

And anytime I mention the word vein, I just want to make sure you think of blood going towards the heart.

A tracheotomy.

And it's actually coming into two veins, the one at the top, this is called the superior, superior just kind of means at the top.

And then you've got the capillaries, you've got some blood kind of from both places the pulmonary circulation and the blood from the systemic circulation again mixing.

Artery up here, artery over here, and then vein in the other two spots.
