I'll write that right here.

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

And it generally travels through two major kind of vessels.

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.

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

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

Into the IV, yes.

So Superior Vena Cava and Inferior Vena Cava.

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.

Start a largebore IV. Keep it open.

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.

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

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'm going to do some surgery here.

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

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.

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

And on the right you actually see a carotid artery that was engineered.

Had some kind of a brain aneurysm.

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

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.

So you think of alternative mechanical parts.

She was being given medicine intravenously.

Now, to start the journey, it's gonna have to out of the left ventricle and into the largest artery of the body.

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

In approximately six months, you will develop a basilar artery aneurysm.

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 you've got another vein from the other lung kind of following a parallel path and going into the veins, as 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.

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.

Coronary vessels So, coronary artery and vein.

So this is more challenging

I can't hear you well.

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.

His pulse increased.

Midway up her right thigh?

Okay.
