All right, so we see when we talk about phagocytosis in the human body, we talk about a quite large, let me say, process where we have ingestion, you know, we have ingestion of particles perhaps larger than 0 .5 micrometers into a plasma membrane, you know, that is, you know, a structure that plasma membrane derives and this structure is what we call a phagosome.
00:40
A phagosome now ingests these, might be bacterial pathogen, let me say, microbial, okay, because it's a human body, then we're looking at microbial pathogen.
00:51
It's what is ingested.
00:53
Also, you might want to talk about apoptotic cells, okay.
01:00
Apoptotic cells also might want to be ingested in this way.
01:04
So, because it's in the human body, we are looking at these two possibilities, or let me say two, perhaps.
01:17
So, it is the same mechanism that, you know, the normal phagocytosis occurs, because we have a whole lot of, let's say, this is the structure, this is the cell, you know, you have a plasma membrane here, we have a large nucleus, plus other structures, you know, lysosomes will be in plenty.
01:52
So, let's call these lysosomes.
01:57
And another thing is the food particle, let me say, bacterial pathogen here, that will be ingested and what will ingest it is a structure that we call a phagosome that also will kind of create a shade around it, okay...
