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

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

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

Disk herniation is when cartilage, called 'intervertebral disk' and found between each vertebra, slips out.

I'll write that right here.

Into the IV, yes.

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

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

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

Start a largebore IV. Keep it open.

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 generally travels through two major kind of vessels.

I'm going to do some surgery here.

Check resisted opposition strength of the thumb to check the median nerve and resisted digit abduction for the ulnar nerve.

They would ordinarily support fish and other wildlife.

And fortunately he didn't die.

Shizuru's bones have been safely buried in the family grave. (In Buddhism, it is believed that a person's soul reincarnates on 49th day. A memorial service is held to celebrate their safe journey into the next life.)

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

It's strange, but it's like deeper it's muscle, vein, nerve, bone.

So Superior Vena Cava and Inferior Vena Cava.

So you think of alternative mechanical parts.

They use a skeleton that we call a hydrostatic skeleton.

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

I just noticed that as I finished this skull, the armature wire that I had been used to holding it up was sticking out of the back just where a spine would be.

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

I hope my veins don't pop.

And my skull's crushed and my collar bone is crushed all but two of my ribs, my pelvis and both arms they're all crushed, but there is still a pulse.

She was being given medicine intravenously.

I have a bulging disk.

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

Palpate anatomic landmarks for tenderness.

If the PSlS moves more cephalad on one side the test is positive, indicating dysfunction.

(English captions by Andrea Matsumoto from the University of Michigan)

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.

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.

Have the patient reach behind the back and up the spine.

No. No.

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.

So if I was to make a volume pressure loop, with this, I could actually erase the word 'balloon' and 'bubble' and replace them completely with 'artery' and 'vein',

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.
