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

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

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.

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.

And, as a result, it's a very good cue to the detailed shape of the skin pore structure and all of the fine wrinkles that all of us have, the things that actually make us look like real humans.

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.
