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

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

And it generally travels through two major kind of vessels.

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

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

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

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.

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 Superior Vena Cava and Inferior Vena Cava.

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.

I'm going to do some surgery here.

It's going to end up at the, maybe I should draw it here, it's ending up with the right atrium. That's just the name of the chamber where the blood ends up in.

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 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.

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

Secondly, it breaks down a lot.

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.

He was also an engineer. He could have rigged pulleys...

I can't really show blue on blue, but you know, just try to see they kind of go there.

So you think of alternative mechanical parts.

She was being given medicine intravenously.

The car came to a smooth stop.

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.

The train came to a smooth stop.

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

I hope my veins don't pop.

Quiet. There's a car coming.

Now on glide path. Mark course.

What materials did you use?

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

And then on the other side where the veins are bringing blood back to the heart most of the blood as it turns out, most of the blood actually goes this way into the pulmonary veins.

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 my spirit soared free,

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.

How well that girl skis!
