About the process of inflammation.
00:03
So just a quick overview of information.
00:05
So say we have some sort of a splinter and all this bacteria or pathogenic material that has entered the body.
00:14
This is detected by white blood cells.
00:17
So here we see white blood cells.
00:20
And the release cytines, which are basically chemical signals that induce more white blood activity to fight against a pathogen as well as mast cells.
00:32
So mass cells are cells that release histamine, and histamine induces visodialation, so the dilation of blood vessels so that even more white blood cells can come to this site of infection and deal with, create inflammation.
00:51
And inflammation obviously is marked by swelling, higher temperatures, pain as well.
00:59
So if we go down this, we'll just see which statement is true.
01:03
So a says inflammation is induced by molecules such as cytokines and histamine that are produced by various host cells in response to pathogens at the side of injury or infection.
01:12
So that is a perfect description of what i gave in our overview of inflammation.
01:16
So that seems like the correct answer, but let's just go down and eliminate the other ones.
01:20
B says during inflammation, all blood cells retreat from the side of infection in order to protect the circulatory system from pathogen infection.
01:26
So the keyword here is all blood cells...
