I'll write that right here.

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

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.

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.

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.

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.

I'm going to do some surgery here.

Start a largebore IV. Keep it open.

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

So Superior Vena Cava and Inferior Vena Cava.

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

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

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.

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

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

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

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.

Coronary vessels So, coronary artery and vein.

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.

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.

They would ordinarily support fish and other wildlife.

And fortunately he didn't die.

So this is more challenging

And the veins actually drain into a spot , directly into the right atrium.

A pulse.

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.

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

So you think of alternative mechanical parts.

She was being given medicine intravenously.

His pulse increased.

Midway up her right thigh?

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

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

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

I hope my veins don't pop.

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.

And so I think we can roll the video that we have.

His vitals are spiking.

Pulse ox 90.

And down here the inferior vena cava.
