Today, we'll be talking about gel electrophoresis.

What is gel electrophoresis, you might ask.

Radial artery pulse and capillary refill testing.

How about wet adhesion? Or capillary adhesion?

Capillary dilation of the socalled blush response?

Evaluate for the radial pulse and capillary refill.

Now, the first vessels, this tiny little vessel over here, it actually is not a capillary, eventhough we would assume it's a capillary,

Here we check radial artery pulse and capillary refill testing.

The PAGE part is PolyAcrylamide Gel Electrophoresis, or we'll just leave it at GE.

Here we demonstrate dorsalis pedis pulse, posterior tibial artery pulse, and capillary refill.

And these are both usually also connected to a big box that contains the gel electrophoresis apparatus.

Here a dorsalis pedis artery, posterior tibial artery, and capillary refill testing are tested.

Here we demonstrate dorsalis pedis artery pulse, posterior tibial artery pulse, and capillary refill testing.

The structure of each villus contains a capillary and lacteal to pick up the digestion nutrients.

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

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.

And so this by definition then, not a true capillary, because it has some smooth muscle in the wall.

And the electrophoresis part of it means that you need to have an electrical field passing through the gel to get the bands to move.

Incidentally, that the gills of fish are bright red is because there are many 'capillary vessels' collected there, the same as for lungs.

So today we've talked about how you would setup a gel electrophoresis, why it works, and how you would want to pick the substance but your gel's made of.

It's capillary action and transpiration pulls water up, a drop at a time, pulling it, releasing it from a leaf and pulling it up through the roots.

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.

So we often talk about capillary beds, but I thought that it would be fun to get really up close and really get a good understanding of how these things work.

Now if we look at animals, though, to be really maneuverable in all surfaces, the animals use hybrid mechanisms that include claws, and spines, and hairs, and pads, and glue, and capillary adhesion and a whole bunch of other things.

But they get the information that causes them to stop, causes them to internalize that they need to make all of the various parts that will cause them to change their shape, and try to get out of this capillary and find out what's going on.

In the lab, we micro pattern channels in the biomaterials on which we grow the cells, and this allows us to flow the cell culture media, the cells' food, through the scaffolds where we're growing the cells a lot like what you might expect from a capillary bed in the heart.
