All right, so to answer this question, i'm going to briefly just kind of go through each one of our answer choices and go through some basic definitions to help us get us to our answer.
00:13
So the first option talks about basophils.
00:17
And basophils are basically just a type of white blood cell in our innate immune system that kind of indirectly attack pathogens.
00:26
They have no real specificity to them.
00:31
If anything, they act indirectly by binding to b lymphocytes, which b lymphocytes from there can produce your ige's, your immunoglobulins, your antibodies against a specific pathogen.
00:48
But basophils themselves are pretty nonspecific.
00:55
Phasylophils, while they can do that, they can play more of an indirect role also through playing a role in inflammation in that whole process.
01:06
And you will also often find them in allergic reactions.
01:11
They can play a role in emitting histamine and that type of thing.
01:16
And also parasitic infections.
01:18
So overall, they're just kind of a white blood cell that kind of goes to the front lines to help some other more specified white blood cells fight a foreign invader.
01:33
Next is regulatory t lymphocytes.
01:37
And these lymphocytes are actually cells that have the opposite effect of most of our immune system cells, in that these cells actually act to suppress the immune system response, and they act to emit cytokines that are anti -inflammatory properties to decrease the reaction, decrease the inflammation that our body is producing.
02:06
And these lymphocytes actually play a really crucial role in preventing chronic inflammatory diseases, and also most especially autoimmune diseases.
02:16
So diseases that develop within us that our cells actually start attacking our own cells.
02:21
For no specific reason, they're not foreign invaders, obviously, but the body does not recognize them that way, so they start getting attacked.
02:28
And this leads to a plethora of diseases and problems down the line.
02:33
So these cells actually play a major role in our bodies have a lot of important significant responsibilities.
02:42
So and then getting into our last choices, which is plasma cell and memory cell.
02:48
These are both types of a b cell and b cells can differentiate to become either a plasma cell or a memory cell.
02:57
So i have that kind of depicted below...
