So this is the peritubular capillary.

Lifesaver pores are 15 nanometers.

How about wet adhesion? Or capillary adhesion?

But these pores here are special.

Also the noise will disappear in these pores.

They get further apart and the actual capillary becomes larger.

Humans and other herbivores, we sweat through our pores to cool ourselves.

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.

A permeable geological formation has pores that permit liquids or gases to pass through.

So the blood's going to come in an arterial that's an arterial capillary, you could say.

I'm not going to do too much detail on the actual cells of the capillary walls.

The average size and density of the pores can be controlled during the manufacturing process.

And now that the space between these capillary cells have gotten further apart, they can get through.

They adhere to the wall, and then eventually they squeeze through these gaps in the capillary wall.

When the heart relaxes, blood is drawn back toward the heart through open ended pores (ostia).

These pores are specialized protein channels that are designed to let sodium rush into the nerve.

One is hierarchical pores, and the other is a macro molecular nanoscale porosity in the material.

Every red blood cell of your body right now has these hourglass shaped pores called aquaporins.

Pores like these conduct electrical current and are responsible for all the communication in the nervous system.

Plants are going to breath in this very same carbon dioxide through pores in their skin, called stomata.

The temperature at which the liquid sample is sucked into the sealed capillary is the boiling point of the sample.

Conceptacles open to the environment via one or many pores, depending on the species and the type of conceptacle.

You can see that the skin pore structure changes enormously from stretched skin pores to the regular skin texture.

The first is the chorion, which is the protective layer that oxygen passes through after entering the shell's tiny pores.

I will show how the capillary action works, how it feeds, I'll be able to get all the cells inside that stem.

As we zoom in on one of these purple neurons, we see that its outer membrane is studded with microscopic pores.

long distance drilling core into the center of rock that we bring up and there's bacteria in the pores of that rock.

The distal's a little bit different so let's say this is a cell, and let's say that this is a peritubular capillary right here.

So these are capillary endothelial cells, and of course, right in here, we have our blood flowing and we'll have red blood cells in here.

And it's also going to have little pores on the outside that will become important when we starting talking about transcription and translation.

Blood brain barrier The blood brain barrier is a part of the capillary system that prevents the entry of T cells into the central nervous system.

Normally, when we leave a capillary system like the glomerulus right there, we're normally dealing with the venous system, but here we're still an arterial system.

But in response to that stimulus the nerve is designed to detect, pores in the cell wall near the receptor of the cell open.

It's a sphere with an opening in here that the capillary can kind of wind around in, and the space right here, this is the Bowman's space.

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.

In 1884, the French microbiologist Charles Chamberland invented a filter (known today as the Chamberland filter or Chamberland Pasteur filter) with pores smaller than bacteria.

They can move rapidly through the pores between soil particles, and are typically found from the surface down to a depth of about 50 cm.

Well, all land plants lose water when the pores on their leaves open up during photosynthesis, and this evaporation draws more water up through their stems.

Because of the size exclusion, the colloidal particles are unable to pass through the pores of an ultrafiltration membrane with a size smaller than their own dimension.

Gravity does not play a role, as it is obvious from the fact that wetting takes place independent of the orientation of the pores relative to the direction of gravity.

And as a golfer and as a kid, one of the things that really sort of seeped into my pores, that I sort of lived my whole life, is process.

We find life at the bottom of every long term, long distance drilling core into the center of rock that we bring up and there's bacteria in the pores of that rock.

The resulting tubes can be removed by mechanical forces for tubes up to 10 µm in length, i.e., by just drawing them out from the pores or by selectively dissolving the template.

But when there's too much of these oily lipids, called sebum, they can plug up the swollen, inflamed pores and trap the pesky, acne causing bacteria inside, where they set up house and thrive.
