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.

It's a safety boundary around the target.

I'll write that right here.

Into the IV, yes.

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

I'm going to do some surgery here.

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

And it generally travels through two major kind of vessels.

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

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

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

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

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.

Give it to me. Please.

So Superior Vena Cava and Inferior Vena Cava.

My eyesight is poor, but my nose is keen.

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

Keep your back straight

What do they mean by schopophobia?

We are here at the... must I look..?

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.

Radial velocities

So you think of alternative mechanical parts.

She was being given medicine intravenously.

I was the only one who could talk to the flight attendants.

Keep your hips straight.

So the thread of discovery that we have really is a thread.

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 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.

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.

When he shouted, the veins in his neck stood out clearly.

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.

She knew. She was... She gave me this look.

But this is not as I said in the beginning bad way of thinking about it.

What have I to be jealous about?

I saw that look between them.

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.

Fellow Rylans, because of a dark betrayal, our Frontier will soon collapse.
