So basically what you're doing is, you're basically completely avoiding this capillary bed, by clamping down on these pre capillary sphincters.

In the capillary.

Or capillary adhesion?

pre capillary sphincters

And this third capillary bed, may be going down to your foot. So you have blood in your foot.

It must be capillary action.

So it's kind of neat use of smooth muscle, to control even at the capillary bed level, where the blood is flowing.

So this is a fenestrated capillary.

Sometimes, they call them capillary beds.

And if they do, let's say we do not want blood to come to this capillary bed, we wanna save the blood for something else.

How about wet adhesion? Or capillary adhesion?

This is our second type of capillary.

These pores are all over the capillary.

It's gonna come down let's say, this way, through the arterial, and let's say some of the blood is gonna continue down this way, maybe to another capillary bed.

Capillary electrophoresis separations can have several hundred thousand theoretical plates.

So let me show you the third type of capillary.

And this one we call this a discontinuous, discontinuous capillary

To bed, to bed!

So you have a capillary that's maybe running right along the surface.

And you might be thinking there's gotta be one more vessel type and there is and that's the capillary. So let me draw the capillary, so I'll do that over here.

And another name for it, discontinuous capillary, is, sometimes they call it sinusoids

And these pre capillary sphincters, what they do is they basically squeeze down.

We went from bed to bed.

This law is valid if the tube radius is smaller than the capillary length.

Any bed is better than no bed.

Go to bed, little father, go to bed.

Now, look in the bed. In the bed?

To introduce the sample, the capillary inlet is placed into a vial containing the sample.

In these systems, a section of the capillary itself is used as the detection cell.

So this red blood cell has moved into the capillary right by this thigh cell.

We worked with a theme, which is, you've got macrophages that are streaming down a capillary, and they're touching the surface of the capillary wall, and they're picking up information from cells that are on the capillary wall, and they are given this information that there's an inflammation somewhere outside, where they can't see and sense.

Now, the first vessels, this tiny little vessel over here, it actually is not a capillary, eventhough we would assume it's a capillary, 'cause it's coming after the arteriola, we call it a metarteriole, a metarteriole .

This is a bed, I know it's a bed.

The bed?

Whose bed?

One bed.

My bed?

Bed stuff.

The bed.

My bed.

In bed.

So when we use the word true capillary , we're really trying to distinguish form that metarteriole.

What the body does this is the nifty concept is that there're these pre capillary sphincters.

I have a bed for you, the bed of Procrustes.

Don't stay in bed, unless you can make money in bed.
